Introduction
31 but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
16 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
Relationship with God began with the love of God. (Jn 3:16)
39 You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me, 40 yet you refuse to come to me that you may have life.
Knowing the Bible will not give life. Knowing Jesus through the Bible leads us to life. (Jn 5:39-40)
27 My sheep hear my voice, and I know them, and they follow me. 28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand.
Those who belongs to Jesus knows His voice and follows Him (10:27-28)
20 In that day you will know that I am in my Father, and you in me, and I in you. 21 Whoever has my commandments and keeps them, he it is who loves me. And he who loves me will be loved by my Father, and I will love him and manifest myself to him.
As we love and obey Jesus, we will know Him and His love more. (Jn 14:20-21)
34 A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. 35 By this all people will know that you are my disciples, if you have love for one another.
Our love for one another communicates our love to Jesus, and communicates Jesus to the world. (Jn 13:34)
15 “If you love me, you will keep my commandments. 16 And I will ask the Father, and he will give you another Helper, to be with you forever, 17 even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.
If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him.
