I have received Jesus Christ and been justified by faith through the finished work of Jesus Christ. Does this mean that I will never have to deal with sin in my life? Let’s take a deeper look into the origin of sin. Adam was given a clear warning in:

but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die.”

 This tree was to reveal whether the future state of man would be good or evil. It would also reveal whether man would allow God to determine for him what is good or evil. The essential nature of sin lies in the fact that man’s will refuses to submit to God’s will. Man should always allow God to determine the course of life. That original sin committed by Adam was transmitted to the entire human race. In the same way God searched for Adam by calling him, God calls us today. If God does not accost our will, our will can never be inclined to God. In his systematic theology Berkhoff states Adam’s sin correctly: “The first sin was a typical character, clearly revealing the essential nature of sin. This lies in the fact that man refused to subject himself to the will of God and to have God determine the course of his life and decided to settle this for himself”. Original sin led mankind into total depravity. Let’s now consider actual sin. This sin is what the Apostle John reminds of us in:

1 JOHN 2:1-2
My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous.
He is the propitiation for our sins, and not for ours only but also for the sins of the whole world.

Christians should always be reminded that when we sin, we sin against God. Actual sin may be sins of the inner life, such as pride, envy, hatred, evil desires and even sensual lust. These sins may also be external such as theft, murder, adultery, and so on. My friend, sin affects our fellowship with God. As Christians surely Christ has taken our sin away at salvation. This is true; however this does not exempt me from being tempted and sinning. This is why Apostle John reminds us about sinning. “I am appealing to you not to sin.” Take note, this is a command given as an exhortation. This is what a Christian does. Paul the Apostle reminds us:

 EPHESIANS 4:22, 24
to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires,24 and to put on the new self, created after the likeness of God in true righteousness and holiness.

This is something that I have to do. We are to work out our salvation with fear and trembling:

Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling,

I have to do that. This is not something that God does for me. God works in us to will and to do according to His pleasure. We have to mortify our members while we live on the earth.

Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry.

I am encouraged to fight the good fight of faith.

1 TIMOTHY 6:12
Fight the good fight of the faith. Take hold of the eternal life to which you were called and about which you made the good confession in the presence of many witnesses.

I am not only encouraged to mortify every member; I am also reminded to lay hold on eternal life (1 Tim 6:12), and to flee from sin and to reckon myself “to be dead to sin”:

So you also must consider yourselves dead to sin and alive to God in Christ Jesus.

This process increases my fellowship with God, not forgetting “God is light”:

1 JOHN 1:6-10
If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth.
But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10 If we say we have not sinned, we make him a liar, and his word is not in us.
