<p>4:13 <em>Hereby we know that we abide in him and He in us, because He has given us of his Spirit</em>- This complements the statement in :12 that we know He abides in us if we live in love. The presence of the Spirit will produce love, the love of Christ, which is the cardinal feature of His entire Spirit. The Spirit is a gift, given- and not cultivated by our own steel willed effort or felicity in Biblical exposition. The Spirit was given when the Lord was glorified (Jn. 7:39); there is a specific gift given to each believer at the time of water baptism.</p>
