Who Can Explain Love?

Psalms 119:174-176 ESV

174 I long for your salvation, O Lord,

and your law is my delight.

175 Let my soul live and praise you,

and let your rules help me.

176 I have gone astray like a lost sheep; seek your servant,

for I do not forget your commandments.

Salvation is through the grace of the Lord. We find this grace because He found us. He seeks us out though we wander and would otherwise be lost. He calls to us each day, that we would be with Him. 

Who can explain or account for this, that we would be worthy of a second thought, or even more, that He would sacrifice Himself for us, that He longs to have us for His children? Who can explain love?
