Because Jesus rose and defeated death, we know we will also be raised. Our hope is eternal life - the glorious privilege of living forever with God. Just imagine living face to face with God forever! No greater privilege could ever be given man.
Importance of Resurrection
Matthew 20:28 Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
John 11:25 - 26 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: And whosoever liveth and believeth in me shall never die.
Romans 5: 6 - 8 For when we were yet without strength, in due time Christ died for the ungodly. For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Ephesians 2:13 - 16 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peacea; And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
1 Peter 1:3 Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
1 John 2:2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
1 John 4:9 - 10 In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.
We can be certain of our resurrection because he was resurrected.
Death is not the end—there is future life.
