In Second Peter, we have an interesting Greek phrase: "…until the day star arise in your hearts." The key word "arise" is anatello. The phrase refers to doctrine arising in your heart to the extent that it totally controls your essence by the Spirit and the Word.
Numbers 24:17 told of a Star that would arise out of Jacob and a Scepter out of Israel. Daniel 12:3 declares that those who lead many to righteousness shall shine as stars. In Matthew 2:2, the star in the east led the wise men to Jesus-the bright and Morning Star.
God wants the "day star" of doctrine to arise in our hearts. He desires that doctrine would come through our human spirit and go down into our heart through the mind, emotions, conscience, self-consciousness, and volition. It will completely take over the streams and rivers of life that flow from God, through us, to others, and back.
Doctrine permeates and perpetuates the life of God’s nature within us when we are filled with His fullness. Every deficiency is filled up. The past with its problems is gone forever. The present is filled with the promise and provision of His power. The future is sure, as we know we are being conformed to Christ’s image in His perfect plan.
