Mark 11:22-24
So Jesus answered and said to them, “Have faith in God. For assuredly , I say to you, whoever says to this mountain, ‘Be removed and be cast into the sea,’ and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says. Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them.”

FROM THE KINGDOM DYNAMICS PORTION OF THE SPIRIT FILLED LIFE BIBLE :
The positive lesson to be learned from the cursing of the fig tree is the power of believing prayer.  A mountain is symbolic of an obstacle, hindrance, or insurmountable problem.  Faith is the key that releases the resources of heaven into our situation.

Jesus on “Faith’s Confession”
From Jesus’ own lips we receive the most direct and practical instruction concerning our exercise of faith.  Consider three points: 1) It is to be “in God.”  Faith that speaks is first faith that seeks.  The Almighty One is the Source and Grounds of our faith and being.  Faith only flows to Him because of the faithfulness that flows from Him.  2) Faith is not a trick performed with our lips, but a spoken expression that springs from the conviction of our hearts.  The idea that faith’s confession is a “formula” for getting things from God is unbiblical.  But the fact that the faith in our hearts is to be spoken, and thereby becomes active and effective toward specific results, is taught here by the Lord Jesus.  3) Jesus’ words “whatever things” apply this principle to every aspect of our lives. The only restrictions are (a) that our faith be “in God” our living Father and in alignment with His will and word; and (b) that we “believe” — not doubting in our hearts. Thus, “speaking to the mountain” is not a vain or superstitious exercise or indulgence in humanistic mind-science, but instead becomes an applied release of God’s creative word of promise.

Mark 11:22-24
Your Faith in God is the Key to Your Receiving, SEED FAITH.  Believing can take opposite forms. It can be faith or it can be doubt.  When you believe that God exists and that He loves you and wants to meet your needs, then your believing creates faith in your heart.
On the other hand, doubt is just as real. The reverse of faith, doubt tells you that God does not exist or that He is unloving and uncaring about your needs. Doubt gives rise to fear, which brings torment, not peace. Fear actually keeps you from receiving the good things God desires to send your way. Capture this truth: Doubt, and do without; with faith believe, and receive. I have said for years, “Expect a miracle!”
Expectancy opens your life to God and puts you in a position to receive salvation, joy, health, financial supply, or peace of mind — everything good your heart longs for and more!

Mark 11:25-26, Forgiveness and Prayer
25 “And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses. 26 “But if you do not forgive, neither will your Father in heaven forgive your trespasses.”

FROM THE KINGDOM DYNAMICS PORTION OF THE SPIRIT FILLED LIFE BIBLE :
Mark 11:25-26 A condition of prevailing prayer is a forgiving spirit (see Matt. 6:14-15).
