Since the old covenant is now obsolete, does this leave us with no moral direction? Absolutely not. The old covenant has been made obsolete to "put legally into place" the New Covenant (2 Corinthians 3:6-9; Hebrews 8:6-13). The life of discipleship flows out of the New Command, to love one another as He loved us (John 13:34), which Paul refers to as the "law of Christ" (Galatians 6:2). Love fulfills the law (Romans 13:8-10). Out of this single command comes other commands, including references for the moral aspect of 9 of the 10 commandments which are reiterated under the New Covenant, yet the command to keep the Sabbath day is not binding on Christians under the New Covenant.
1. You shall have no other gods before Me. - Acts 14:15
2. You shall make no idols. - 1 John 5:21
3. You shall not take the name of the Lord your God in vain. - James 5:12
4. Keep the Sabbath day holy. - Not binding on the Church - Colossians 2:16-17
5. Honor your father and your mother. - Ephesians 6:1-2
6. You shall not murder. - Romans 13:9-10; 1 John 3:15
7. You shall not commit adultery. - Romans 13:9-10; 1 Corinthians 6:9-10
8. You shall not steal. - Romans 13:9-10; Ephesians 4:28
9. You shall not bear false witness against your neighbor. - Romans 13:9-10; Colossians 3:9-10
10. You shall not covet. - Romans 13:9-10; Ephesians 5:3
