Why Resurrection?

2. Reasons for Resurrection
To show that God approved Jesus’ sacrifice

I Corinthians 15:17 And if Christ be not raised, your faith is vain; ye are yet in your sins.
Power in Resurrection
Romans 6:4 Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

3. Motivation to Live for God Because of Hope
Philippians 4:10 that I may know Him and the power of His resurrection, and the fellowship of His sufferings, being conformed to His death,
Paul’s life (I Corinthians 15:9-10)
Glorified Body
I John 3:2 Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is.  
Motivation to Live for God Because of Hope
I John 3:3 And everyone who has this hope in Him purifies himself, just as He is pure.

Jesus, the Firstfruits
