Most assuredly I tell you, we speak that which we know, and testify of that which we have seen, and you don't receive our witness.

 Here then we have three great kindred conceptions, entry into the kingdom of heaven, sonship of God and eternal life; and all are dependent on and are the products of perfect obedience to the will of God. It is just here that the idea of being reborn comes in. It is what links all these three conceptions together. It is quite clear that, as we are and in our own strength, we are quite unable to render to God this perfect obedience; it is only when God's grace enters into us and takes possession of us and changes us that we can give to him the reverence and the devotion we ought to give. It is through Jesus Christ that we are reborn; it is when he enters into possession of our hearts and lives that the change comes.
