Jesus is the one sent by God to save us.
Here we can see that Jesus Christ is the one sent by God and he is the one who brings the divine message, here we understand that Jesus Christ in everything he has done was always under the order of God.
Here in this text he also speaks that God loves his son very much, he granted him all power, this means that God is incarnated in his son. Jesus is the word of God, he is the verb made flesh, everything that God said is done in Jesus.
And God shows his love for us that he has sent the most precious thing he had, his son, his nature to die for us and save us, Jesus is God himself made flesh and he has all the power, our security is placed in Jesus who will help us in everything. With this text we can understand that God is inviting us to fully trust in him and in the sacrifice of Jesus Christ, following his teachings through the word of God and entrusting our lives into his hands to live fully here on earth and for eternity.
Because the one whom God sent speaks the words of God, for God does not give the Spirit by measure. 35 The Father loves the Son and has put all things into his hands.
John 3:34-35
