When was the last time you watched your husband or wife complete a significant life accomplishment? How about watching one of your children win a sporting competition or graduate? What other milestones do we celebrate?
The Bible says we are to rejoice with those who rejoice and weep with those who weep (Romans 12:15). How does that work most often? We are going through sorrow, difficulty, or trials and we engage others to pray for us and encourage us. That would certainly fall under the idea of weeping with those who weep. That is a good thing. But what about the other part of that verse: rejoice with those who rejoice?
Someone put the Scripture in a modern context and said, “If God had a refrigerator, your picture would be on it!” God loves His children more than we can know or describe. When God sees His child learn to take up the towel of sacrificial service, He rejoices. When He sees His child love the unlovable, He rejoices. When He sees His child forgive as He forgives, He rejoices. These are “milestones” in Christian living. Just like you applaud your graduating child or your winning child, I believe God applauds the steps His children take to become more like Him. How does he do it?
First, God personally rejoices. When a person comes to faith in Him, He rejoices. God will personally exult over His children with His own singing and dancing. Those are great moments, but we can’t hear them from here. How does heaven’s applause reach our earthly ears? Heaven’s applause is made with your hands! Which brothers and sisters are you encouraging with God’s applause? How often are you clapping? Think about it.
 Luke 15:10
 Zephaniah 3:17
