All things were created through Him and for Him (Col 1:16)

In him was life, and the life was the light for humanity (John 1:4)

You [God] created all things, and on account of your will they were and were created (Rev 4:11)

So why would we live for anything other than God’s eternal purpose in Christ?

Those whom he foreknew, he also decided in advance to be conformed to the image of his Son, so that he would be the firstborn among many siblings; and whom he decided in advance, these he also called; and whom he called, these he also put right with himself; and whom he put right with himself, these he also glorified (Rom 8:30)
