He Is Risen!
O death, where [is] thy sting? O grave, where [is] thy victory? The sting of death [is] sin; and the strength of sin [is] the law. But thanks [be] to God, which giveth us the victory through our Lord Jesus Christ. 1 Corinthians 15:55-57
We can celebrate that Our God is alive and not in grave as some other religions because He is Risen and is sitting on the right side of His Father. If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Colossians 3:1
