Isaiah 60:19 The sun shall be no more thy light by day; Neither for brightness shall the moon give light unto thee: But the LORD shall be unto thee an everlasting light, And thy God thy glory.
Amazingly, we see this same truth taught in the New Testament. There will be no need of the sun and moon. Jesus will be the light of the city. God is all that we need. He meets our needs. He is our everlasting light. Notice the promise word, everlasting.
Death is not the end. We are not temporary beings. We live forever, somewhere. If you are born again then God has a place of blessing and glory for you. God is everything to all who will believe. If you have not trusted Him for your salvation then today is your day.
