Did you know that the 4000 years, between Adam and Y'shua, were an object lesson that points to a solution for mankind's predicament?
The problem, with that, is there was not and never could be a perfect human, born of man, since disobedience now resided in the very nature of man. Since no man, born of a man/woman union, is perfect, God had to provide a solution. The solution was to provide a man through an undefiled woman impregnated by the Spirit of God. This resulted in the supernatural birth of Y’shua, Jesus.
According to scriptures, The Tanakh, The Old Testament, where God revealed to us his salvation plan, Y’shua was borne with the Spirit of God and of a virgin woman. He lived a perfect life as a man and was crucified upon the alter of God, the Cross. During his crucifixion, the scriptures tells us that he was made sin for us all. On the cross or stake, God withdrew himself from the man Y’shua and left the perfect Y'shua, to die upon the cross, as the ultimate sin offering.
He was buried in a tomb, guarded by Roman soldiers.
As a side note, the Jewish leadership feared that the followers of Y'shua would steal the body and claim resurrection. They asked Pontius Pilate to secure the tomb. Pontius Pilate was the Roman Prefect in Israel at this time and the one who condemned Y'shua to death. Pontius Pilate makes a great comment. He said, "Make it as sure as you can." That meant a minimum of four soldiers would guard the tomb for the length of Pesach, Passover.
Later, on Shavuott, Pentecost, Y'shua ascended to his rightful place, the right hand of his Father in Heaven, where he makes intercession for us on a daily basis. With his blood, he is now a sin covering for all of us who relies on that sacrfice for reconciliation with God.
The only thing God requires from any of us is to accept and believe that Y’shua was the perfect sacrifice.
After that, when we confess ours sins to him, he will be faithful and just to forgive us.
As part of the new relationship, a true believer will desire to get to know God on a more intimate basis through his Word and understanding how his creation reveals him to all. Usually, the first act of obedience of a true believer is to follow Y’shua and be baptized. Baptism is being immersed in water to publicly display your dedication to a life in the Messiah and a ever-growing close relationship with God.
