"For all things are yours, and ye are Christ's; and Christ is God's" (1 Cor. 3:21,23).
When you were born into the family of God, the right and privilege to use the Name of Jesus became yours. Everything Jesus bought and paid for automatically became yours. But it's up to you to use what belongs to you.
The elder brother became angry, and wouldn't go in and join the festivities. So his father went outside and entreated him. "No, I'm not coming in," the elder brother said, "I've served you faithfully all these years. I never went away. I didn't go off and spend your money – and you never made a feast for me." "Son," the father said, "All that I have is thine" (Luke 15:31).
Does God have what you need? If He does, then it is already yours. But you'll have to appropriate it.
Confession: All things are mine. I am Christ's, and Christ is God's. The Name of Jesus belongs to me. I can use it. I will use it. All the Father has is mine!
