Now the next day, when they had come out from Bethany, He was hungry. 13 And seeing from afar a fig tree having leaves, He went to see if perhaps He would find something on it. When He came to it, He found nothing but leaves, for it was not the season for figs. 14 In response Jesus said to it, “Let no one eat fruit from you ever again” . . . 20 Now in the morning, as they passed by, they saw the fig tree dried up from the roots. 21 And Peter, remembering, said to Him, “Rabbi, look! The fig tree which You cursed has withered away.” 22 So Jesus answered and said to them, “Have faith in God. 23 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. Mark 11:12-14, 20-23 NKJV
Jesus demonstrated and taught His disciples the principle of prophetic power. When faced with a mountain (figurative)—a challenge, some difficulty, or what seems to be an impossible situation; if you have faith in God, then God can do anything, according to the spirit of faith. “We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak” (Ps. 116:10; 2 Cor. 4:13). The spirit of faith is prophetic power.
Jesus operated with words of prophetic power, teaching His disciples the mechanics of navigating the spirit of faith and exercising prophetic power: say it, don’t doubt it, believe it and receive it, and you shall have whatsoever you say (Mark 11:23). The spirit of faith can be exercised with both positive and negative words. Jesus used negative words to curse the barren fig tree (Mark 11:14).
You can bless or curse with the words you speak (prophesy). You can also save your life and lose your life by what you say, i.e., by your own prophetic power (Prov. 18:21). Your words spoken will prophesy grace, favor, and righteousness or prophesy guilt, condemnation, and judgment against you (Matt. 12:37).
So, watch your mouth! You have immense power; you will have what you say (prophesy). There are consequences, outcomes, and results as the direct fruit of the words we prophesy. Words are never lost spoken in the atmosphere. Remember the prophet Samuel—as he grew, “the Lord was with him and let none of his words fall to the ground” (1 Sam. 3:19). Nor will the Lord allow your words to fall to the ground. Again, watch your mouth. “Whoever guards his mouth and tongue keeps his soul from troubles” (Prov. 21:23).
