John 1:1, 14, 16-17

In the beginning [before all time] was the Word (Christ), and the Word was with God, and the Word was God Himself. [Gen 1:1; Is 9:6]

And the Word (Christ) became flesh, and lived among us; and we [actually] saw His glory, glory as belongs to the [One and] only begotten Son of the Father, [the Son who is truly unique, the only One of His kind, who is] full of grace and truth (absolutely free of deception). [Is 40:5]

For out of His fullness [the superabundance of His grace and truth] we have all received grace upon grace [spiritual blessing upon spiritual blessing, favor upon favor, and gift heaped upon gift]. For the Law was given through Moses, but grace [the unearned, undeserved favor of God] and truth came through Jesus Christ. [Ex 20:1]
