that we love one another
Law (of Christ), Summary:
The new "law of Christ" is the divine love, as wrought into the renewed heart by the Holy Spirit (Romans 5:5); (Hebrews 10:16) and outflowing in the energy of the Spirit, unforced and spontaneous, toward the objects of the divine love; (2 Corinthians 5:14-20); (1 Thessalonians 2:7); (1 Thessalonians 2:8). It is, therefore, " the law of liberty"; (James 1:25); (James 2:12) in contrast with the external law of Moses. Moses' law demands love, (Leviticus 19:18); (Deuteronomy 6:5); (Luke 10:27) Christ's law is love; (Romans 5:5); (1 John 4:7); (1 John 4:19); (1 John 4:20) and so takes the place of the external law by fulfilling it; (Romans 13:10); (Galatians 5:14). It is the "law written in the heart" under the New Covenant.
