Sunday Night Teaching - John 14 - The infancy of believing

1 John 3:1-3 KJV

Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
And every man that hath this hope in him purifieth himself, even as he is pure.
