Very truly, I tell you, anyone who hears my word and believes him who sent me has eternal life, and does not come under judgment, but has passed from death to life. “Very truly, I tell you, the hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live. For just as the Father has life in himself, so he has granted the Son also to have life in himself; And the Father who sent me has himself testified on my behalf. You have never heard his voice or seen his form, and you do not have his word abiding in you, because you do not believe him whom he has sent. “You search the scriptures because you think that in them you have eternal life; and it is they that testify on my behalf. Yet you refuse to come to me to have life. (John 5:24-26,37-40, NRSV)
“You search the scripture to find eternal life, yet they testify about me and you will not come to me,” Jesus said here.
The whole of the scripture Hebrew and New Testament point to Jesus as the Messiah, and yet we still search there for eternal life?
Jesus is the way, the truth and the life, through Him we come to the Father.
So testify to Jesus.
