There is a popular expression that says "seeing is believing." However, many people saw the amazing signs performed by Jesus and did not believe in him. In two separate incidents recorded in John 4:43-5:18, Jesus performed signs of healing, but few believed in him. One politically connected man did believe while the religious leaders did not. He became a model of faith, while they became a warning about the dangers of man-made religion. (full sermon notes)
While the people cynically questioned God’s justice and longed for his intervention, in Malachi 2:17-3:5, God told them he would be coming in judgment...
God fulfills his plan against human opposition and even through human suffering.
As opposition grew toward Jesus, he anticipated that it would reach his followers as well and prepare them for how to live.
