Sin is bad. We know this.
However, we often choose to sin anyway.
Why should we stop allowing ourselves to indulge in sin?
 For to be carnally minded is death; but to be spiritually minded is life and peace.
Well, I want life and peace, don't you? And besides,
 Because the carnal mind is enmity against God… So then they that are in the flesh cannot please God.
I want to please God, too.
 Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
 For if ye live after the flesh, ye shall die…
And I certainly don't want to die! I want to live!
…but if ye through the Spirit do mortify the deeds of the body, ye shall live.
If I am in the Spirit, I am God's child:
 For as many as are led by the Spirit of God, they are the sons of God.
If I am His child, then I am His heir and have available to me all that is in Christ:
 And if children, then heirs; heirs of God, and joint-heirs with Christ…
And if I suffer with Him, I will be glorified with Him:
…if so be that we suffer with him, that we may be also glorified together.
So then…by mortifying the flesh (refusing to meet the sinful demands of my body), as a child of God, I will be glorified with Him.
But is it really worth it? Heaven seems so far away sometimes. My sin is not "bad" sin…it's just a little sin. I'm not hurting anybody with it. I'm not a murderer, for goodness' sake!
Why should I give up my sin?
 For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.
Do I want God's glory to be revealed in me? You betcha!
Is it hard to give up sin, to turn to Christ in obedience? Oh yeah!
Does my sinful flesh demand its rights? Daily.
Is it worth it to see sin as it truly is…disobedience against my Father God? Most definitely!
Romans 6: Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
 Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
God promises that the suffering we may endure by refusing to sin cannot even be compared to the glory that He will reveal in us.
Let's take Him at His Word…
And turn from our sin!
