And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
Christ being the anointed of God the Father means that He was the chosen One to be the Savior of the world. Christ was chosen because who He was and He met all of the Father's required qualifications to atone the sins of the world.
If the question was raised, what were the Father's requirements to atone the sins of the world? The person was required to be human and divine and without sin. Christ was both human and divine as He was God in the second person in the Godhead. Christ was able to keep all of God's commandments and His atoning works was a one-time event whereas the earthly priests' atonement was performed yearly. The earthly priests required that their sins be forgiven whereas Christ had no sin.
That said, God being God knew from the beginning of time what was going to occur and He had a redeemer ready and waiting until the appointed time to fulfill His mission.
It is noteworthy to say all of God's actions are a manifestation of His love, grace and mercy for humanity. Man is created in the image and likeness of God; man was created to be in fellowship with Him but sin broke that fellowship and Christ's atoning work on Calvary restored the fellowship.
What a mighty God who loved humanity to the point He gave His only begotten Son to be the sacrificial lamb.
