Don’t let kindness and truth forsake you. Bind them around your neck. Write them on the tablet of your heart. So you will find favor, and good understanding in the sight of God and man.
I will also give you a new heart, and I will put a new spirit within you. I will take away the stony heart out of your flesh, and I will give you a heart of flesh.
For most certainly I tell you, whoever may tell this mountain, ‘Be taken up and cast into the sea,’ and doesn’t doubt in his heart, but believes that what he says is happening, he shall have whatever he says.
