Rom 6:14 For sin shall not have dominion over you: for ye are not under the law, but under grace.
Imagine something with me for a moment.
Imagine yourself with one of two things hanging over your head.
Either an ominous, deadly weight of the moral law is hanging precariously over you, dangling by a worn and frayed rope with only a few threads remaining intact. Every time you fail, another thread snaps and the load of the law drops another inch. You surmise that soon, you are going to be crushed by the weight of the law. This is a picture of the person outside of Christ, condemned by his sin and disbelief.
Or, you are overshadowed by the kind hand of God. Being far from perfect, you are deserving of any judgment that might fall upon you, but that gracious hand which hovers over you protects you from any hurt or danger. This is the state of the one who has been forgiven and washed in the blood of Jesus. This believer is covered by grace; unmerited, wonderful, amazing, protective, overcoming, abounding, redeeming grace.
Thank God that He has placed His Holy Spirit within us, His angels all around us and His graceful hand over us.
And because of this blessed state, we should walk accordingly. We should act like we are saved. Sin no longer dictates our actions, we are free to love and serve Jesus.
It is said that before we were saved, we ran to sin, now that we are saved, we run from sin. When we were shadowed by the law, sin dictated our actions, when it said "jump" we asked, "how high?" Now, as we are covered by grace, when sin dictates that we jump, we have the power to say yes or no. Because of our position under grace, we are able to refuse sins dictates.
