1 Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, 2 through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God. (Romans 5:1–2, NKJV)
The great grace of God is accessed by faith. Abraham’s faith is prototypical of the faith we must have in order to access grace (Rom. 4). Those who “walk in the steps of the faith” that Abraham had are those who are saved (Rom. 4:12-16). Notably, Abraham’s obedience perfected his faith (Jas. 2:21-24). In the same manner, obedient faith grants access to God’s grace today (Rom. 6:17-18). One greatly errs if he thinks God’s grace overlooks sin. “What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it” (Rom. 6:1-2)? Faithful Christians will not develop a careless attitude toward what sin is, or toward what it does. The Holy Spirit warns us not to fall from grace, and persuades us to live by faith by obeying the “perfect law of liberty” (Gal. 5:4; 2 Cor. 5:7; Jas. 1:22-25). Do not falsely conclude that because God’s grace is so great, it will save you in spite of having unrepented sin in your life. That is not the faith of father Abraham. That will never be the faith that accesses and stands in grace.
