3:13 ascended up to heaven. This is an emphatic claim to deity, as Christ here refers to Proverbs 30:4, and appropriates it as applying uniquely to Himself, thus claiming to be the only begotten Son of God. Not even David had yet “ascended into the heavens” (Acts 2:34), but Jesus had descended from heaven (note also John 3:31), and would soon ascend back to heaven (John 20:17) and even now (by virtue of the indissoluble union of the triune Godhead) was still “in heaven.”
