IN [this] freedom Christ has made us free [and completely liberated us]; stand fast then, and do not be hampered and held ensnared and submit again to a yoke of slavery [which you have once put off].
Anytime a believer in Christ is trying to get right with God, they do not understand as the church at Galatia did not fully understand, that you cannot by your own merit be made right with God. Righteousness is a free gift that we receive. Anyone who accepts Christ as their Savior has received this gift or you have not been born again. Those who are trying to get right with God by their own works are living under a yoke of slavery.
This does not mean that once we have received this gift it is bondage to now walk in obedience to the Word of God, which would be doing what is right in God’s sight. Because we have become right with God, we now have this new man on the inside who desires to do what is right. As we yield to our spirit man, we do what is right outwardly because our spirit who is recreated in the image of God desires to do so.
We do what is right in God’s sight not to get right with Him, but because we already are right with Him. It is this outward obedience to God and His Word that helps us to not give in to the ways of the old outer fleshly nature. When we walk in the spirit, choosing to do what our new nature desires which is in line with God’s Word, we do not fulfill the lusts of the flesh. So choose to do what is right in God’s sight not to get right with God, but because you already are right with Him.
