In both the Old and New Testaments, commandments are repeatedly mentioned and we are repeatedly exhorted to obey and follow them. So why do Christians not need to obey and follow the 10 commandments from Moses (or any other Biblical commandments for that matter)?
Romans 8:2 - ...through Christ Jesus the law of the Spirit of life set (us) free from the law of sin and death.
I believe that these commandments have been revealed by Jesus to be guidances to be obeyed only at those times when the Holy Spirit moves upon us to do so.
A time to plant and a time to uproot what is planted.
A time to kill and a time to heal;
A time to tear down and a time to build up.
A time to weep and a time to laugh;
A time to mourn and a time to dance.
A time to throw stones and a time to gather stones;
A time to embrace and a time to shun embracing.
A time to search and a time to give up as lost;
A time to keep and a time to throw away.
A time to tear apart and a time to sew together;
A time to be silent and a time to speak.
A time to love and a time to hate;
A time for war and a time for peace.
Romans 8:3 - 14 - For...(we) do not live according to the sinful nature but according to the Spirit.
Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires.
The mind (allowed by us to be) controlled by the Spirit is life and peace;
...(for our inherently)... sinful mind is hostile to God. It does not submit to God's law, nor can it do so. Those controlled by the sinful nature cannot please God.
You, however, (should allow yourself to be) controlled...by the Spirit, if the Spirit of God lives in you....
because those who are led by the Spirit of God are sons of God.
