โ€œHow do I know whether Iโ€™ve crossed the line in my mindโ€”how do I discern whether it’s temptation or sin?โ€

This is a frequent question I get asked at our Harvest USA groups. While there could be mixed motivations for asking such a question, I believe the most common reason Christians ask this stems from a very legitimate desire to please their heavenly Father. At the core of our identity as adopted sons and daughters of God in Christ, we have been given hearts that long to hear our Father say, โ€œWell done, good and faithful servant.โ€

Temptation or Sin? Christians Want to Please God

We know that sin displeases our Father. So how does God look upon us when we wrestle daily, and frequently throughout the day, with desires, thoughts, and temptations that we know are not pure, good, or pleasing to God? Do these weaknesses count as temptation or sin? Is God always frustrated and dishonored by our lives?

This is an important question for the believer who wants to repent well of ongoing patterns of sin. Believing that God is pleased with our repentance is a powerful motivation to continue repenting.

Believing that God is pleased with our repentance is a powerful motivation to continue repenting.

But if we think that all of our sincere efforts are only met with perpetual disappointment from our Father, then it will only be a matter of time before despair sets in. And eventually, we give up.

This is an especially significant question for men and women wrestling with same-sex attraction. They can struggle with great discouragement if every experience of same-sex attraction is classified as sin. But no matter what form temptation presents itself, these deep questions concern everyone.

We all know the pain of never measuring up to someoneโ€™s standards. It may be a child whose parents arenโ€™t pleased with any grade below an A+, or an employee whose boss never gives them a compliment, or someone who never experiences their spouseโ€™s delight in them. This hurts, and over time, it can be a crushing experience. So too, brothers and sisters wrestling with ongoing temptation want to know that God is pleased by their sincere efforts to fight sin.

In light of these good desires to please God, how should we understand the nature of sin, temptation, and our hearts? How do we discern whether something is temptation or sin? This is the topic of much current discussion. My purpose here is not to throw my two cents into the conversation, since I believe a historic, reformed anthropology adequately reflects the biblical teaching on sin and temptation. My concern is more with the pastoral implications of this anthropology.

So, I will briefly summarize my understanding and then explain how this does not lead to despair in the Christianโ€™s life, but hope! Itโ€™s helpful to consider three categories when conceptualizing whether something is temptation or sin:

1. Temptation from Without

This is temptation to sin that comes at you that has no genesis in sinful desires. Adam and Eve were tempted from without by the serpent. Jesus was tempted from without by the devil. When someone entices you to engage in sinful activity, this is temptation from without. It does not come from your heart but is seeking to tempt your heart to sin.

2. Temptation from Within (Indwelling Sin)

This is temptation that arises from corrupt desires in your heart. James says that โ€œeach person is tempted when he is lured and enticed by his own desireโ€ (James 1:14). How are we to understand the moral quality of these desires? Are they neutral?

I donโ€™t believe the Bible allows that interpretation. These desires are sinful desires, arising from the fallen, corrupted, sinful nature that we have all inherited from Adam. Another term for temptation from within is โ€œindwelling sin.โ€ A very important feature of indwelling sin is that it is not something consciously chosen or something that we willfully summon. And yet, it is still sin.

3. Voluntary (Willful) Sin

If temptation from within is not something we consciously choose, then voluntary sin is what we willingly engage in. This is what most people think of when they think of sin. They think of something that is willfully chosen. And indeed, much sin is of this variety.

We’re presented an opportunity to sin, and our hearts desire it. Now we’re left with a choice. Will we turn to Christ, or give in to our sinful desires? This is what James means when he says, โ€œThen desire when it has conceived gives birth to sinโ€ (James 1:15). James is not saying the desire itself was not sin, but that sinful desires, often unbidden, give birth to willful sin.

At first, this might sound crushing to someone wrestling with sinful desires on a daily basis. Indeed, it should sober us to think of the overwhelming weight and pervasiveness of our sin. That sin is not just something we occasionally do, but sin impacts every willing act in our lives.

Consider the call of Christ to โ€œlove the Lord your God with all your heart, and with all your soul, and with all your mindโ€ (Matt. 22:37). I donโ€™t believe there is a single moment of my life where I can say this was perfectly true of me. Pride and selfishness always infect even the purest motivations of my heart.

Sin is not just something we occasionally do, but sin impacts every willing act in our lives.

This must mean God is constantly disappointed in you, right? Wrong! Christ came not only to die in my place for the sins that I continue to commit, but also to live the perfect life that I never could. We can never merit favor with God by our own righteousnessโ€”our own good intentions or efforts. This is why Christโ€™s active and passive obedience are required to earn our full salvation. No one will be accepted into Godโ€™s presence unless they have a record of proven, perfect righteousness. Christ alone has accomplished this, and by Spirit-wrought faith we are united to Christ in all of his benefits, including his justification becoming our own.

Union with Christ and God’s Approval

So, instead of crushing the believerโ€™s heart, sin should greatly deepen our appreciation of the gospelโ€”the good news of Christโ€™s life, death, and resurrection for us! The more we come to grips with how bad the bad news really is, the more we come to worship, delight in, and love our Savior.

This understanding of Jesus-for-us is the answer to our concern that we can never please God, even though we’re saved, because indwelling sin stains everything we do. But the Bible gives us so many declarations that God delights in his people and is pleased by their obedience (Rom. 12:1โ€“2, Gal. 1:10, 1 Thess. 2:4). Is it perfect, sinless obedience, worthy of salvation? No. But every Christian can and does obey in ways that delight our heavenly Father.

The Westminster Confession of Faith explains this possibility of pleasing God so well in section 16.6:

Notwithstanding, the persons of believers being accepted through Christ, their good works also are accepted in Him; not as though they were in this life wholly unblameable and unreprovable in God’s sight; but that He, looking upon them in His Son, is pleased to accept and reward that which is sincere, although accompanied with many weaknesses and imperfections.

This is so crucial to understand! How are our sincere efforts to please God acceptable in his sight if they are not perfect? They are accepted by God โ€œthrough Christ,โ€ as God looks upon our imperfect works โ€œin His Son.โ€

Jesus’s Sympathy and Delight in His Battling Children

Hereโ€™s the answer, then, to the question: How do I know if Iโ€™ve crossed the lineโ€”how do I discern whether something is temptation or sin? We are always crossing the line between temptation and sin because we are fallen. We donโ€™t just need the gospel to save us from Godโ€™s wrath, we need the gospel to do anything that pleases the Father.

This means that when you’re wrestling with indwelling sinโ€”temptations from withinโ€”you have the opportunity to please God! When you turn from corrupt desires rising up from within your heart, when you make war with your flesh, and when you submit to the Spirit leading you into the throne room of grace, you are met there by your High Priest with sympathy and delight.

Every Christian will battle indwelling sin until they see Jesus face to face. This will be a daily, moment-by-moment battle. Godโ€™s not disappointed in you because you’re fighting against indwelling sin. The very opposite: He calls you to never give up fighting sin. The ones who meet God and hear the words โ€œwell done, good and faithful servant,โ€ are those who endured to the end. Who didnโ€™t make peace with their sin, but continued to take up their weapons of warfare that we see so beautifully outlined in Ephesians 6.

Godโ€™s not disappointed in you because you are fighting against indwelling sin. The very opposite: He calls you to never give up fighting sin.

Brothers and sisters, you arenโ€™t laboring in vain. Not only are your sincere, Spirit-dependent efforts accepted and rewarded in Christ, but they are also sowing seeds into greater and greater righteousness. You donโ€™t โ€œbox as one beating the airโ€ (1 Cor. 9:26), but instead, you are being transformed into the image of Jesus Christ, from one degree of glory to another (2 Cor. 3:18).
