What part in the Bible is God's covenant?

Answer 1

God has made several covenants in The Bible. The first was with adam, of course. As long as they would obey him i.e not eat from the forbidden tree, they would enjoy direct relationship with him. Then there was the covenant with the patriachs, all in Genesis. Another covenant was made, or a continuation of the old one, depending on how you look at it, with david. This can be found in first or second kings. All christians benefit from this covenant.

Answer 3

In John 13:34-35 Jesus gives a new commandment. Keeping it is what will identify a true follower of Jesus Christ.

“A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.”

Matthew 26:28

"For this is my blood of the new covenant, which is shed for many for the remission of sins."

Also it's reiterated in Luke 22:20 and Mark 14:24.
