1:14 the Word became flesh. This is the climactic assertion of the Prologue. To some of John’s contemporaries, spirit and the divine were utterly opposed to matter and flesh. To others, the gods were thought to visit the earth disguised as human beings (Acts 14:11).

These words correspond to Old Testament terms describing God’s covenant mercy that are often translated “steadfast love and faithfulness” (Gen. 24:27; Ps. 25:10; Prov. 16:6; cf. Ex. 34:6; Ps. 26:3). The Word made flesh fully manifests the gracious covenant-making and covenant-keeping character of God.
