Isaiah 55:11 So shall My word be that goes forth from My mouth; it shall not return to Me void, but it shall accomplish what I please, and it shall prosper in the thing for which I sent it.
God has given you the privilege of quoting His Word, and then expecting Him to honor it. He loves to see you expect Him to stand behind His promises. Many claim that miracles were to get the Church started in the days of the apostles, but are no longer available. God has a different idea, because He wants you to believe for miracles in this century as well. First identify the need, next identify the promise in the Bible that will apply to it. Thirdly ask the Lord what His will is, then bring the need and the promise to God in prayer, reminding Him of His promise. Faith is depending that God is going to honor His Word in spite of the circumstances. There may be oppositions to faith, but your faith must stand on the Word of God.
His Word cannot lie, His Word will never let you down - but His Word is useless unless you follow the Prescription and USE it!
