“Have faith in God,” Jesus answered. “Truly I tell you, if anyone says to this mountain, ‘Go, throw yourself into the sea,’ and does not doubt in their heart but believes that what they say will happen, it will be done for them. Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours.” – Mark 11:22-24  

“Have faith in God” is a simple command to those of us who are walking with God. It’s a mystery to those who are not intimate with Him.

Faith always requires some fact or evidence to rest upon because faith can only be exercised where the will of God is known. The promises of God are the will of God in those particular areas. Why else would God make a promise if He had no intention of fulfilling it?

The word of God is filled with promises we can use in prayer if we believe them. To have faith that a promise will bring an answer when we pray, we must have faith in God who made the promise in the first place. We can only have faith in Him if we know Him. 

This is exactly what Jesus meant in Mark 11:22. When we come to know a person of integrity, we come to trust that person. Trusting the person causes us to believe what they say…the same is true with God. …Just a thought
