Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you… – Matthew 7:7

On the throne of grace sovereignty has placed itself under bonds of love. God will do as He wills; but, on the mercy seat, He is under bonds-bonds of His own making, for He has entered into covenant with Christ, and so into covenant with His chosen. When I come to God in Christ, to God on the mercy seat, I need not imagine that by any act of sovereignty God will set aside His covenant. That cannot be: it is impossible… The covenant contains in it many gracious promises, exceeding great and precious. “Ask and it shall be given you; seek and ye shall find; knock and it shall be opened unto you.” Until God had said that word or a word to that effect, it was at His own option to hear prayer or not, but it is not so now; for now, if it be true prayer offered through Jesus Christ, His truth binds Him to hear it. A man may be perfectly free, but the moment he makes a promise, he is not free to break it; and the everlasting God wants not to break His promise. He delights to fulfill it. He hath declared that all His promises are yea and amen in Christ Jesus; but, for our consolation when we survey God under the high and terrible aspect of a sovereign, we have this to reflect on, that He is under covenant bonds of promise to be faithful to the souls that seek Him. His throne must be a throne of grace to His people. And sweetest thought of all, every covenant promise has been endorsed and sealed with blood, and far be it from the everlasting God to pour scorn upon the blood of His dear Son… It is not possible that we can plead in vain with God when we plead the blood-sealed covenant, ordered in all things and sure. Heaven and earth shall pass away, but the power of the blood of Jesus with God can never fail. It speaks when we are silent, and it prevails when we are defeated. ~ C.H. Spurgeon
