Mark 11:23
I assure you and most solemnly say to you, whoever says to this mountain, ‘Be lifted up and thrown into the sea!’ and does not doubt in his heart (in God’s unlimited power), but believes that what he says will be done for him.
What are we speaking to ourselves internally and to those around us? Are we using our words and faith to move mountains, or are we speaking doubt and unbelief? It matters for our futures what we believe and whether we are talking ourselves out of a victory. The Bible is here to help us conquer our fears and will tear down the mountain when we speak the word in faith.
