10 “The Lord of Hosts is with us; the God of Jacob is our taker up”. Not any man, not any power, not, in short, Angel, or any creature either earthly or heavenly, but “the Lord of Hosts is with us; the God of Jacob is our taker up.” He who sent Angels, came after Angels, came that Angels might serve Him, came that men He might make equal to Angels. Mighty Grace! If God be for us, who can be against us? “The Lord of Hosts is with us.” What Lord of Hosts is with us? “If” (I say) “God be for us, who can be against us?
He that spared not His own Son, but delivered Him up for us all; how has He not with Him also freely given us all things.” Therefore be we secure, in tranquillity of heart nourish we a good conscience with the Bread of the Lord. “The Lord of Hosts is with us; the God of Jacob is our taker up.” However great be your infirmity, see who takes you up. One is sick, a physician is called to him. His own taken-up, the Physician calls the sick man. Who has taken him up? Even He. A great hope of salvation; a great Physician has taken him up.
What Physician? Every Physician save He is man: every Physician who comes to a sick man, another day can be made sick, beside Him. “The God of Jacob is our taker up.” Make yourself altogether as a little child, such as are taken up by their parents. For those not taken up, are exposed; those taken up are nursed. Do you think God has so taken you up, as when an infant your mother took you up? Not so, but to eternity. For your voice is in that Psalm, “My father and my mother forsake me, but the Lord has taken me up.”
