Ideas about the Kingdom of the Heavens around us and the unity of believers in Christ within it
True repentance would have required high priest Eli to act to remove his sons Hophni and Phinehas from office. Hophni and Phinehas were using God and their offices as a magical charm and using others, as many in the Church do today. The people also learned to do these things from their example. Instead of removing them, Eli just nagged them, and he and all Israel paid the penalty.
In Luke 13:1-9, Jesus answers the “problem of evil” by pointing at his questioners’–and everyone’s–sin, pointing out that death and suffering come as a result of sin, not of being a greater or lesser sinner, and calling for repentance.
The parables of the lost sheep, the lost coins and the two lost sons, one of them the “Prodigal son,” in Luke 15 show our value to God, God’s search for us, and our returning to him, or not, in repentance, and teach why we should not be judgmental toward those who appear great “sinners.”
Simon Magus was told to repent of his attempt to buy the Holy Spirit. We should also repent of our modern forms of claiming we can possess God for our own use or profit.
