(John 14:15-17) If you love me, keep my commands, And I will ask the Father, and he will give you another advocate to help you, and be with you forever–the Spirit of truth. The world cannot accept him because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.
(Romans 8:14 & 16) For those who are led by the Spirit of God are the children of God and verse 16, The Spirit himself testifies with our spirit that we are God’s children.
