The final words of Jesus from the Cross declare the mission He was to accomplish, for your sake and mine.
Luk 23:34 Then Jesus said, "Father, forgive them, for they do not know what they do." And they divided His garments and cast lots. He forgave those that crucified him, then took away His garments. When we receive His forgiveness, we walk away in His royal garment of righteousness.
Mar 15:34 And at the ninth hour Jesus cried out with a loud voice..,"my God, my God, why have you forsaken me? When He became sin for us, His fellowship with His Father was interrupted so we could find complete acceptance with our Heavenly Father.
Joh 19:28 After this, Jesus, knowing that all things were now accomplished, that the Scripture might be fulfilled, said, "I thirst!" The Cross was a triumph and because He perfectly fulfilled the Messianic promises, every promise God ever made to man, is freely ours, that we may never thirst again.
Luk 23:46 And when Jesus had cried out with a loud voice, He said, "Father, 'into Your hands I commit my spirit.' Jesus had committed His body to love people and finally provide the blood atonement for us. He then offers His spirit to continue the Father's mission in His journey to heaven via hell, so that our victory over Satan is complete.
Joh 19:30 So when Jesus had received the sour wine, He said, "It is finished!" And bowing His head, He gave up His spirit. Everything required to set mankind free from despair, death, disease and the devil was finished in order to usher in life and a new beginning for all those that believe and receive His Spirit.
Behold what manner of love the Father has bestowed upon us that we should be called the sons of God. The Son of God became as sin for us, so sinners could become the sons of God.
