When reading the Bible, please take into consideration the verses before and after.
Isaiah 49:14 "But Zion said, The LORD hath forsaken me, and my Lord hath forgotten me.
Isaiah 49:15 "Can a woman forget her sucking child, that she should not have compassion on the son of her womb? yea, they may forget, yet will I not forget thee.
Isaiah 49:16 Behold, I have graven thee upon the palms of my hands; thy walls are continually before me."
GOD is saying to Zion, it may feel like I've left you and although a woman has compassion on the child she bore; and may forget, GOD never forgets us for HE has each of us in mind continually!
I told you guys HE carries a picture of me in HIS wallet. lol!
