How do we know that Jesus is full of grace and truth?

The assurance that Jesus is full of grace and truth comes from Scripture itself. In John 1:14, the Apostle John declares that he and others beheld Jesus' glory as the only begotten of the Father, highlighting His unique position in revealing God. Additionally, John 20:31 states that events recorded in Scripture are aimed at leading us to believe in Jesus as the Christ, thereby underscoring His divine nature and promises. Our faith is based on the truth of who He is and what He has accomplished, particularly His sacrificial death and resurrection, which affirms His grace as the sole source of salvation for humanity.
