Martin Luther stated one of the most important redemptive truths in this manner: Simul Iustus et Peccator. It means “at the same time justified and sinners.” I have been a Christian since I was 27 years old. That was almost 34 years ago. The moment I believed I had Christ’s righteousness imputed upon me. Yet, I still committed sin. After 34 years, I still commit sin! I remain, at the same time, justified and sinner. Some believers, because they live relatively good moral lives, have a tendency to see themselves as really good people. This is a very dangerous thing. They think that because they have not outwardly done wicked deeds like committing murder, getting intoxicated, stealing, or lying that they actually goes days and weeks without sinning. They reason that while they certainly must sin every once in a while, they really do live a life very pleasing indeed to God. Allow me to briefly point out some of the real problems with this kind of thinking.
1. A Very Shallow View of Sin
We must go beyond viewing sin as outward acts of great injustice toward our fellow man. Sin is primarily against God. David when confessing his sins of adultery and murder recognized this truth clearly when he stated, “Against you, you only, have I sinned and done what is evil in your sight” (Psalm 51:4). David’s sins, in this case, were grossly immoral outward acts that he tried to cover up. However, when we begin to see sin as against God, we can then look for what God requires of us in His commandments. Clearly, when all of Scripture is considered, we must see how far short we fall continually. All we have to do is consider what Jesus called the great commandment: “You shall love the Lord your God with all your heart and with all your soul and with all your mind” (Matthew 22:37). Consider also what Paul wrote in I Corinthians 10:31: “So, whether you eat or drink, or whatever you do, do all to the glory of God.” These two verses alone should cause us to recognize our continual failure to follow God’s law completely. Sin is not a minor thing. Not loving God is a major problem. Not glorifying God is wicked beyond our comprehension. We sin against God and we must see and feel this very deeply. A very shallow view of sin leads to another problem.
2. A Diminishing Appreciation for the Gospel
The Puritan pastor Thomas Watson wrote, “Till sin be bitter, Christ will not be sweet.” If we recognize our sins, even realizing that we can’t track all of them, we will be constantly living in the light of the cross of Christ. We will constantly be aware that He is our only hope. We will preach the gospel to ourselves continually. We will grow in our amazement of His grace in forgiveness. All believers must come to a clear recognition that they always and only can stand right before God based on Christ’s righteousness. “But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it-the righteousness of God through faith in Jesus Christ for all who believe” (Romans 3:21,22). Put negatively, all believers must clearly realize that they can never stand before God based on their own performance. We are always, at the same time justified and sinners. Now, if one has a very shallow view of sin and, thus, is not coming continually to the cross, a third problem emerges.
3. A Sanctification Tied to One’s Own Doing and Not to Christ
Justification and sanctification are distinct aspects of salvation. Yet, they are inextricably linked together. It is not merely that both are necessary parts of salvation. This is true. But it is also true that sanctification cannot happen apart from justification. Also, we must say that sanctification happens from out of our justified position in Christ. If you are a believer, your sanctification (spiritual progress into Christlikeness) in part of God’s complete redemptive plan, happens by His grace, is God’s work, and is tied to your being justified and in Christ. When we see ourselves as good people, who infrequently sin, we no longer actively and continually embrace the gospel and, thus, do not grow in the strength that gospel grace provides. Notice how Paul begins His closing doxology in Romans 16:25: “Now to him who is able to strengthen you according to my gospel and the preaching of Jesus Christ.” Instead of growing through the gospel and gospel proclamation and explanation (preaching and teaching), a believer is in danger of becoming proud, self-righteous, and self-reliant. Let’s consider one final problem.
4. The Absence of Doing Battle with Sin
If sin isn’t a problem anymore, then we must not waste time dealing with it. However, if we understand both our justification and the fact that we still sin, we can actively engage in spiritual warfare—and do it from a position of victory! The fact is that sin is still a real problem in our lives. Though we are in Christ, on our day to day journey, we still struggle with indwelling sin. Thus, there are many New Testament imperatives to “put away” or “put off” sin (see Ephesians 4:22,31; Colossians 3:8; James 1:21; I Peter 2:1). These imperatives must be applied in light of the gospel indicatives. This means that our obedience comes out of our reliance on Christ’s work alone. Apart from Him we can do nothing (see John 15:5). Christianity is not a religion asking you to become what you are not. The Christian teaching is that we become in practice what we are in position. Since we have died with Christ and are risen in His new life, let’s be alive to God in our practice (Romans 6:11). However, Let’s do this in humble dependence not in self-reliant and proud performance.
So no matter how long one has been saved, a believer is still a sinner after all of his/her years. This should not be a discouragement because we are already in Christ and justified. Not only that, but He is working in us for our sanctification. Not only that, but He will finish the work and bring us into the fullness of His kingdom. We know this because He has already accomplished the victory. He Himself has risen from the dead and sits in the exalted place at the right hand of the Father. He will come again according to His promise. How great is the outcome. Listen to how Paul puts it in Colossians 3:4: “When Christ who is your life appears, then you also will appear with him in glory.”
