Jesus told this
Be careful not to practice your righteousness in front of others to be seen by them. If you do, you will have no reward from your Father in heaven. “So when you give to the needy, do not announce it with trumpets, as the hypocrites do in the synagogues and on the streets, to be honored by others. Truly I tell you, they have received their reward in full. But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you.
Matthew 6:1-4
But today Christian preachers are doing this
Why do these Christian preachers blatantly disobey the words of Jesus?
1) It is because they want to be popular.
2) It is because they do ministry for business
3) They can use these photos in which they pose as if they are helping others for raising funds
4) They serve themselves and not Jesus.
Jesus hates such ministries. But still these people use the name of Jesus in their ministries and do business. God will judge them on his day. Let us not pass judgment on these guys. Their deeds judge themselves.
