God chose His elect for a great purpose. All who were selected by God for salvation should live with the realization that there is an eternal purpose and specific design for their lives. All believers have been saved “for good works, which God prepared beforehand, that we should walk in them” (Eph 2:10). Like salvation, the “good works” of a believer were preordained by God before the foundation of the world. So there is something for us in this world that has been eternally prepared by God. For this reason, the believer should live with a sense of eternal destiny. He should know that God has gone before him and determined what will be his contribution to His kingdom. Living with an eternal perspective requires that we boldly enter into the fullness of the good works that God has prepared for us to accomplish.
May you not waste your life. Invest it wisely. And may you realize what God has ordained for you to do from before the foundation of the world.
