I thought I could have leaped from earth to heaven at one spring when I first saw my sins drowned in the Redeemer's blood. –Spurgeon
And these things write we unto you, that your joy may be full. 1 John 1:4
When somebody realizes Jesus died for THEM and they ask the Lord to save THEM, a peace that passes all understanding comes over them they have never felt before. It’s as if a huge burden is pulled out of their heart and joy fills the emptiness that sin has weighed them down with. Tears of joy start trickling down the cheeks of the repentant sinner. Chuckles of joy start to leap out of the heart. A settled joy of knowing everything is going to be just fine. Why does this joy fill our life, because Jesus fills our heart with the joy no one else can give—a lasting joy. What a reminder of this everlasting joy in Isaiah 51:11, “Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.”
