No single person was born-again before the cross
No one who walked with Jesus during His three and one-half years of public ministry was Born Again, was a New Creation, or had Eternal Life. No one under the First Covenant had Eternal Life until the Day of Pentecost.
But someone may ask, didn't the disciples believe in Jesus? Yes, but not as their Substitute, not as their Savior who was going to die and rise again from the dead. They believed in Him as the Son of God, as a Great Prophet, as the One who was going to redeem them from the Roman yoke and establish again a Jewish nation. They knew nothing of His Substitutionary work.
In John 11:25-27 we read the story of Martha and Jesus' onversation about the dead Lazarus. Jesus said, "I am the resurrection, and the life; he that believeth on me, though he die, yet shall he live; and whosoever liveth and believeth on me shall never die. Believest thou this?
She saith unto him, Yea, Lord: I have believed that thou art the Christ, the Son of God, even he that cometh into the world." She did not believe in Him as a Savior.
Everything before the cross is part of the Old Covenant, which means for the biggest part of His life on earth, Jesus lived His life as a Jew, under the law. Gal 4:4 But when the set time had fully come, God sent his Son, born of a woman, BORN UNDER THE LAW, 5 to redeem those under the law...
If you absolutely HAVE TO live your life by commandments and principles, but still wish to stay in the New Covenant, well here is one for you.
1 John 3:23 And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment.
Under the new covenant, the only commandment required is BELIEVING.
Even if a man Keeps all the 612 laws, Still he can not please God Because the law is not of faith & without faith you can't please God.
The new covenant can be distinguished from the old in that it is a covenant you can never break
The old covenant was underwritten by your frail promises to God, but the new rests on the “better promises” of God himself (Heb 8:6). In the old you loved God and forgave others because it was commanded of you, but in the new you love and forgive because the "Lover" and the 'Forgiver" lives on the inside of you.
The old covenant was between God and Israel, but the new covenant is between God the Father and God the Son. God holds up both ends of this arrangement, swears by himself, and gives us his Spirit as a guarantee of what is to come (2 Cor 1:22).
Under the old covenant, you were blessed if you obeyed, but under the new you are blessed because Christ obeyed. Your salvation is eternally secure because it is Jesus who saves and keeps you.
Man says "I will" and breaks his word again and again(Exodus 19:8)
God says "I will" and keeps his word forever and ever( Hebrews 8:8-12)
