Ex 12:22-51; Lk 15; Job 30; 1Co 16

Surprise and joy in the finding, or revealing, of the elect.  
Luke 15
7 I tell you, in the same way there will be more joy in heaven over one sinner who repents than over ninety-nine righteous people who have no need to repent.
10 In the same way, I tell you, there is joy in the presence of God’s angels over one sinner who repents.”
32 It was appropriate to celebrate and be glad, for your brother was dead, and is alive; he was lost and is found.’”

1 Corinthians 16
13 Stay alert, stand firm in the faith, show courage, be strong. 14 Everything you do should be done in love.
