“When my father and my mother forsake me, then the LORD will take me up.”

“Be free from the love of money, content with such things as you have, for he has said, “I will in no way leave you, neither will I in any way forsake you.””

“teaching them to observe all things that I commanded you. Behold, I am with you always, even to the end of the age.” Amen.”

“God sets the lonely in families. He brings out the prisoners with singing, but the rebellious dwell in a sun-scorched land.”

“Don’t you be afraid, for I am with you. Don’t be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness.”

“I will not leave you orphans. I will come to you.”

“Where could I go from your Spirit? Or where could I flee from your presence? If I ascend up into heaven, you are there. If I make my bed in Sheol, behold, you are there! If I take the wings of the dawn, and settle in the uttermost parts of the sea, even there your hand will lead me, and your right hand will hold me.”
