Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound: That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord. Romans 5:20-21
Grace has been assumed to be an abstract quality, lacking tangibility, but that is not true, I am convinced from study of Scripture that grace is the Power of God working in a believer through the Holy Spirit.
There has been this great misconception that grace affords the Christian to sin and get God to overlook such behaviour, that is to sin and not be held accountable.
That’s not what scripture communicates to us, from Romans 5:20 Paul was trying to make clear to us that where there was much sin, much more power (grace) was given to live above sin. Then in verse 21 he clarifies it further by saying that sin had its way leading to the ultimate consequence of death but now grace came with a power that afforded men to live righteous possessing in it the power which was above death, which we call eternal life.
Romans 5:17 tells us that death reigned in us because of the sin of one man but the much more shall we whom have received abundance of grace and gift of righteousness shall reign in life by one man Jesus Christ. Implying just as we had no option but to fall under the power of Sin when Adam fell so also Grace came with a power to afford us live above Sin.
Considering 2 Corinthians 12:9 God said to Paul, My grace is sufficient for you, for my strength is man perfect in weakness. Then Paul said, Most gladly therefore I will rather glory in my infirmities, that the power of Christ may rest upon me.
This didn’t mean that Paul was left to suffer his weakness but that God had already made provision for over coming such weakness. So Paul understood that grace he received was the power of Christ that would rest upon him permitting him live life above that weakness.
In ending 1 Corinthians 15:10 Paul declared that ‘But by grace I am what I am: and his grace which hr bestowed upon me was not in vain; but I laboured more abundantly then they all, yet not I, but the grace of God which was in me.
It was grace that afforded Paul do the exploits he did.
Grace is the power of God working in the believer by the agency of the Holy Spirit affording him to live the God life.
