God greatly rejoices

I tell you, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance. (Luke 15:7 ESV)

Jesus emphatically makes the point that God has great joy when someone comes to salvation. “More joy in heaven” would be understood as saying that “God greatly rejoices” over the sinner who repents.
 As God seeks out the lost, we are often the tools He uses in that search. One of our jobs as Christians is to share the gospel with those in need. Do we keep an eye out for those He may be leading us to? And when we are face to face with someone in need of God’s love and truth, do we take the steps necessary to witness to that person and to express His message?
  Are we willing to be winsome, to show God’s love to all, including the downtrodden, the rough types, those who in today’s world are rejected and looked down upon? Are we willing to mingle with the lost in order to show them God’s unconditional love and salvation?
 May we each emulate the nature and character of God in our interactions with those in need of His love and salvation. —Peter Amsterdam [1]

 Each time anyone comes in contact with us, they must become different and better people because of having met us. We must radiate God's love. —Mother Teresa
