For sinners (including believers): the Law, itself, increases transgressions (Rom 5:20), for the Law is the power of sin (1Cor 15:56). For saints (believers): on the basis of the Gospel (accomplishments of Christ), the Spirit (Gal 5:22) himself, produces in us the righteous requirements of the Law (Rom 8:4), Love (Gal 5:14).
a) For we are led by the Spirit, and thus not under the Law. (Gal 5:18)
b) For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery. (Gal 5:1)
c) For we were called to freedom, brothers; thus, through Love (NOT LAW) serve one another. (Gal 5:13)
