The end of the matter is this: our duty as humans is to worship and obey God. That's why we exist, that what we were designed for, and that's what gives our lives meaning. Obeying God should not be burdensome, as if God simply wants to oppress us and not allow us to have any fun. Obedience helps us realize our true purpose and should bring us great joy. It also helps us to not fear when God judges our every deed. In the end, we should remember God while we're young and not procrastinate a life of faith in Him.
