Have you noticed the similarities between a power cord and the Trinity? Think of this, God is the power that feeds our needs while Christ intercedes on our behalf. The Holy Spirit is what keeps us grounded.
Black Wire = Power coming in
White Wire = Return to source
Copper Wire = Ground
2 Peter 1:3 (NIV)
3 His divine power has given us everything we need for life and godliness through our knowledge of him who called us by his own glory and goodness.
