Isaiah 50, 51
In the millennial reign and thereafter, God has appointed that HIS CHILDREN shall enjoy an eternity of joy. It shall be upon our heads like a crown. All sorrow and mourning will have been replaced by His eternal happiness.
This life presents us with occasions of sorrow and pain. Those days will be gone. Our light affliction here shall be for just a moment. Not only will /God take it away, but He gives us His grace as a down payment on the glory to come. He helps us endure and says, “Be of good cheer. I have overcome the world.”
