Love covers all sins.
That's a pretty powerful statement. But can we in some way see even more clearly how powerful it is?
Let's think about light and dark. You can stand in a cave - far from the light filtering in through the opening - and see nothing. Before such an experience in fact - you might have not really experienced total darkness.
Whether that space is the size of a football stadium - or a small room ... light a candle in the depths of that cave - and the power of light will impress you. A mere candle's of light is utterly transforming.
Darkness has no such power - at least - I've never heard of anyone measuring "darkness" by it's "candle power." Darkness in fact is better understood as the absence of light - than the presence of "dark".
If we compare the "dark" of sin to the "light" of love ... I'd argue that the power of light still prevails - because the work Jesus' Love completed on the cross vanquished sin's darkness. Jesus lit a light over the shadow of sin for all time. The light He lit was love - and it was love that motivated Him to suffer to light it.
Love was God's motivation for making everything - and it's pull on us is so strong that virtually all our favorite stories revolve around it. This hunger in us for love is as much God's thumb-print on us as the pull in us to search for Him. Love heals. Love cleans. Love builds. However much we spend of ourselves to pursue His love - He rewards us exponentially. It's as if our little gifts of love to Him - are like the little drops of oil left in the widow's jar (2 Kings 4) - which He multiplies over and over to sustain us in our journey closer to Him. Such is the power of God's love for us. This isn't to say that our journey is always easy, or even always as clear as we'd like. But we can find reassurance that this Love of His - which He created from nothing just like everything else - is infinitely inexhaustible. Our lack of clarity and our struggle to find it has nothing to do with Him and everything to do us. His efforts to help to submit and surrender to His will. His love is so great though - that all that submission and surrender not only helps us see Him more clearly - but become more who He made us to be.
Now that is God's powerful love. Love covers all darkness.
