God promises, “I will be the same until your old age, and I will bear you up when you turn gray. I have made you, and I will carry you; I will bear and save you.”
God tells us He is never-changing. He is the same yesterday, today, and tomorrow. As He is here for us now, so shall He be there for us then; as He was there for us at our births, so He will be there with us at our physical deaths. As He loves us now, so will He love us then.
He “will bear [us] up when [we] turn gray.” He “will carry [us].” He will “save [us].”
