For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith. Mark 11:23 KJV
The power of God responds to your words spoken in faith believing.
There is nothing that can stand against the constant profession of the believers faith. Words spoken from a heart filled with faith cannot fail because faith is empowered by the God kind of Love.
Love never fails. . . (1 Cor. 13:8)
For [if we are] in Christ Jesus, neither circumcision nor uncircumcision counts for anything, but only faith activated and energized and expressed and working through love. Galatians 5:6 AMPC
Remember, the source of faith is consistently listening to the Eod of God.
So then faith cometh by hearing, and hearing by the word of God. Romans 10:17 KJV
