20My son, be attentive to my words; incline your ear to my sayings. 21Let them not escape from your sight; keep them within your heart. 22For they are life to those who find them, and healing to all their flesh. 23Keep your heart with all vigilance, for from it flow the springs of life.
Mark 11:23 ESV
23Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him.
