Jesus said that the Father has life in Himself. He added that the Father has given to the Son to have life in Himself (John 5:26). And you must see what a grave mistake it would be to say, “And, yes, the Father has also granted me to have life in myself. Amen and amen.” No, no amen to that. The Father has not granted you to have life in yourself. He has granted you to have life. But that life is found in Him. It is His liveliness that is your life.
The great temptation that lurks in the marshlands, that temptation that would suck you down and snuff out your life, is the temptation to live apart from God. It is the temptation to go about your coaching, teaching, summering, purchasing, cooking, exercising, and all of your other ings in the same exact way unbelievers do. This can be tricky. Unbelievers coach, and teach, and summer, and purchase. You are doing the same activities, after all. But you must do them as what you are, which is one who has been brought into the life of the fully-alive Trinity.
If you attempt to go about your living severed from Him, you will have as much sweetness and flavor as one of those molded blueberries at the bottom of the container you forgot was in the back of the refridgerator. God has brought you into the bond of His covenant, and in that covenant He has given you life, a big wide world, an array of gifts and good works to enjoy. So resolve to never live outside of that bond of the covenant. The life you live, you live by faith. The life you enjoy is the life of the Trinity, which never grows old or stale.
