What is glorification?
“Dear friends, we are God’s children now, and what we will be has not yet been revealed. We know that when He appears, we will be like Him, because we will see Him as He is.”
— 1st John 3:2
When God completes our salvation, setting believers totally free from temptation, and making them like Jesus.
They will know God fully, and receive a glorified body suited for Heaven. It will be wonderful and will last forever.
