The Reason for Being
What is the chief end of man? So goes Q1 of the Westminster Larger Catechism (I’m paraphrasing). Answer: To glorify God and enjoy him forever. That’s why we exist, to make much of God and bask in the rays of his infinite splendor.
This God of whom we speak is Triune, and his Triune nature helps us understand why we exist. In the Trinity (that great Mystery) there are Three divine Persons eternally existing in and as the One God. These eternal relations of procession are reflected in the way God works in and through his creation. All created things have their being from God the Father, in God the Son, and by God the Spirit, even in their fallen state. In salvation, the Father sends the Son to win our salvation for us. The Father and Son then send the Spirit to apply our salvation to us. In doing so, the Spirit glorifies the Son, and the Son in turn glorifies the Father, directing all things back to him. In salvation, all things return to the Father, by the Spirit and in the Son.
And that’s why you exist. To turn back to your Maker. To turn all the things he sends your way back to him in praise and thanksgiving. That’s why your today exists, to move everything under your influence back to him. This is the reality. Get swept up in the Trinitarian glory right now by trusting the Father to forgive your sins through the death of his Son, by the power of his Spirit, to the praise of his eternal glory, and he will wash your sins away and embrace you forever and ever.
