When you believe and act upon any promise of God, your life will be transformed and you will experience the power of God. Every promise of God contains the power of God necessary to produce what it promises, when it is believed and acted upon. If, under the old covenant, millions of God's people could be well at one time, then how much more may God's people be well today who are living under the new covenant of mercy, grace, and truth, established on better promises, with a better priesthood, through a more excellent ministry.
