Answer:
For of Him and through Him and to Him [are] all things, to whom [be] glory forever. Amen.(ROMANS 11:36).
ZEPHANIAH 3:17, 1 CORINTHIANS 10:31, 1 PETER 4:11
Many, many people, young and old, have asked similar questions. What is my purpose? Why did God create me? The answer is very simple and very clear in the Bible. God created us to glorify Him and to enjoy Him forever. We were created by Him and for Him. He did not need us because He was lonely or wanted someone to talk to. God is perfect and complete and has always been that way. We belong completely to Him. Because of that, we are to glorify Him in everything that we do. How do we do that? We love Him, obey Him, believe in Jesus Christ, trust in Jesus, receiving the free gift Jesus offers us . . . only then will we give glory to God, and only then we will be able to enjoy Him forever, for all eternity!
