It's the heart that pumps the blood. Without the heart to pump it - the blood is useless. It's the same for the Body of Christ. If we don't surrender our hearts to God, if we don't love him with our hearts (love resides in the heart, not the mind), then the blood of Jesus is useless to us. We may claim the Blood as the atonement for our sins but our hearts must be transformed by His abiding presence within us - our hearts must be fully given to Him, for the blood to keep us alive. Our hearts beating for Him cause His blood to cleanse us daily of sin's impurities. Jesus testified that many honor Him with their lips but their hearts are far from Him. He also testified that many will claim they are His servants, prophesying in His name, caring for the poor and strangers, all in His name, all without ever having known Him. I believe these are people who only know of Jesus as an intellectual concept in their minds but never surrender their hearts to Him, they never knew him heart to heart! He's given his heart to us, he loves us with all his heart, can we do any less for Him? Deep calls out to deep. Heart cries out to heart. His heart is calling out to ours - let's become one....
"Arise my love, my fair one, and come away"
"I sleep but my heart waketh, it is the voice of my beloved that knocketh, saying OPEN TO ME"
"Love is strong as death"
"Make haste my beloved"
