20 He was destined before the foundation of the world, but was revealed at the end of the ages for your sake. 21 Through him you have come to trust in God, who raised him from the dead and gave him glory, so that your faith and hope are set on God. 1 Peter 1:20-21
Throughout the whole history, God was and is the main director behind all that have happened. Jesus was destined to be the Savior even before God established the world. Hence, the fall of humans did not come as a surprise to God; He knew it right beforehand. It was the plan of God that Jesus would be born at that particular time of the history and it was then, that people began to realize the Sovereign plan of God in saving humanity in the person of Christ.
Now with the way being made for us by Christ Jesus, we put our trust in God having that assurance that as Christ was raised from the dead and glorified Him, so also those who put their hope and faith in God will be quickened by God’s power to resurrection and life. It is the promise from God with the sign of Christ’s glorious resurrection from the grave.
