God is the source of truth, life, and salvation throughout Scripture.
Psalm 27:1; Psalm 86:11; Deuteronomy 32:4 provide broad background.
Jesus is not merely one guide among many. Access to the Father is exclusively through him, and the disciples' future is described as being with Jesus.
Placing faith in Jesus alongside faith in God and locating life and access to the Father in Jesus is strongly Christological.
