Grace is favor from God. Some take this favor as license to sin. Since they think God’s grace has forgiven them, actions diminish in light of abounding grace. I appreciate the applause for grace, but cringe at the application.
Shall we sin that grace may abound? No. Turning grace into lasciviousness is equal with denying the Lord Jesus Christ.
Grace teaches us to deny ungodliness and worldly lust, and to live soberly, righteously and godly in this present world.
If you like sin, being taught to not sin doesn’t seem like much of a favor!
It is not until one grows in understanding of the offense of sin that one can truly see grace abounding.
Once grace is grasped, sin loses its lustre. Sin’s slow death in our actions creates rejoicing in God’s grace.
Those who speak of sin lightly because of grace merely show their ignorance, lack of faith, and trample under foot the Lord Jesus Christ. If you have no desire to stop sinning, then you have no desire for God’s grace.
“That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.”
anti-itch meditation 
Anything that is not of faith is sin, so when a believer is worrying about funds to pay their rent, or money for food, they have stopped trusting in Christ, started to focus on the problem instead of God, and this is a biblical description of sin, to stop trusting God. This description of sin seems fairly tame, worrying about how to pay your bills, compared to lusting over porn and giving in to one’s fleshly desires. So anyone who says they have not sinned has made themselves a liar, we all are sinners. Our behavior is just an outward reflection of our heart, folks bound up in worrying about their life, are just as sinful as the guy sitting in front of the computer viewing porn.
The just shall live by faith, but what does that mean exactly, it means trusting all the promises of God in the person of Jesus Christ. Grace allows us to see the beauty of God, He removes the blindness to see all that He is in Christ, someone whom we can trust totally. When we are not seeing Christ clearly, sin creeps in, by faith we cry out to God to help us to see Him more clearly. God promises to meet all our needs, we need His help to see that in His word, and to hold on to those promises by faith. The only way to defeat sin is by trusting in God’s promise to be our total heart’s satisfaction, and to meet every need by His grace. God rewards all those who diligently seek Him.
