God loves us very much. Zechariah is about the depth of that love. In response to God’s love for us we’re called to return to him from our wayward ways. 
We’re called to trust Him, obey Him, Worship Him, and above all recognize Him. In Chapter 9, verse 9, we read, “Look, your King is coming to you…riding on a donkey, riding on a donkey’s colt.” Can you think of a less threatening figure?
But they did not recognize Him. Rather, they executed Him. Chapter 12, verse 10 says, “I will pour out…a spirit of grace and pleas for mercy, so that when they look on me, on him whom they have pierced…they will mourn as one mourns for an only son.” These prophetic passages from Zechariah are clearly references to the coming Messiah, Jesus Christ. There is no greater expression of God’s Love than that which we see expressed on Calvary. God pours out his grace through Christ upon all who will receive it. Jesus lifted up the “plea for mercy” for us when he said to the Father, “forgive them, for they know not what they do.” It’s all about the depth of God’s love for us.
Billy Graham wrote, “God’s love provides the plan and way of redemption for sinful man. God’s love is the cross of Jesus, by which man can have forgiveness and cleansing. It was the love of God that sent Jesus Christ to the cross! Never question God’s great love, for it is as unchangeable a part of God as His holiness. No matter how terrible your sins, God loves you. Were it not for the love of God, none of us would ever have a chance in the future life. But God is Love and his love for us is everlasting!”
