Since Creation, down the ages, men and women, when called upon by God, have stepped out in faith to do His bidding. They were the least likely individuals to accomplish God's purpose, but they were men and women who had a faith that could move mountains!
And their faith came from "hearing the Word of God".
When God instructed Noah to build an ark of cypress wood, he went ahead and built the boat to God's exact measurements. He was ridiculed by everybody for building a boat with no water anywhere around, but Noah had heard the Word of God, and he stepped out in faith to do His bidding, and thereby, he and his family found salvation when God unleashed the Deluge to destroy the wicked world (Gen).
Even though Abraham and his wife Sarah were well past child-bearing age, God fulfilled His promise to give them a son. God also promised Abraham that his son, Isaac, would give him descendants numbering as many as the stars in the sky. So, when God asked Abraham to offer his only beloved son to Him, on Mount Moriah, did Abraham hesitate?
No, he stepped out in faith to do God's bidding, because he had heard the Word of God, and he knew Yahweh would fulfill His promise (Gen). Moses, who murdered an Egyptian, was hiding in Midian when God spoke to him from a burning bush, and commissioned him to bring out the Israelites from the bondage of Egyptian slavery, to "a land of milk and honey". Moses stepped out in faith to do God's bidding, and shepherded the Israelites to the threshold of the land God had promised them, because he had heard the Word of God assuring him, "I will be with you" (Ex 3: 7 -
While the Israelite armies, led by King Saul, trembled and fled before the giant Philistine, Goliath, a young shepherd boy, David, stepped out in faith to do battle "in the name of the Lord of hosts, the God of the armies of Israel" (1Sam 17: 45). As he told Goliath, "...for the battle is the Lord's and He will give you into our hands" (1Sam 17: 47). This shepherd boy, filled with the Spirit of the Lord, armed only with a sling and five pebbles, prevailed over the giant, fully-armed, fully-armored Philistine!
Faith always played a crucial part in the signs and wonders worked by our Lord Jesus Christ during His short ministry on this earth. From curing the leper, or the paralytic lowered through the roof, or the twelve years hemorrhaging woman who touched His cloak, it was their great faith that brought about their cure. From curing the Roman centurion's servant, to bringing to life Jairus' dead daughter, it was their great faith that helped to accomplish the extra-ordinary events.
If you want to have a faith that can move mountains, what you say is very important. Remember, when Jesus cursed the fig tree and it withered away? Peter pointed out the fact to Jesus, who replied: "Have faith in God. Truly I tell you, if you say to this mountain, 'Be taken up and thrown into the sea,' and if you do not doubt in your heart, but believe that what you say will come to pass, it will be done for you" (Mk 11: 22 - 23).
The key phrases here are "do not doubt in your heart", "believe that what you say will come to pass" and "it will be done for you". From this, it follows that you get what you think in your mind, believe in your heart and speak with your mouth. So, to have a faith that can move your mountains of failures, your mountains of sickness, your mountains of financial problems, or your mountains of relationship problems, you have to get out of the habit of letting your thoughts and words dwell on your health problems, weaknesses and failures.
Rom 10: 17 tells us: "Faith comes from what is heard, and what is heard comes through the Word of Christ." So, fill your mind, heart and mouth with the Word of God. Tackle your mountains of financial problems by memorizing and repeating often: "And my God will satisfy every need of yours according to His riches in glory in Christ Jesus" (Phil 4: 19), and "The Lord is my shepherd; I shall not want" (Ps 23: 1). Tackle your mountains of failure by memorizing and repeating frequently: "I can do all things through Him who strengthens me" (Phil 4: 13). Tackle your mountains of health problems by memorizing and repeating frequently: "By His wounds you have been healed" (1Pet 2: 24).
Remember, these are God's words that you speak, and there is power in the Word of God. You will develop a faith to move your troublesome mountains as you hear the Word of God flowing from your lips.
