Many people today thinks that pastor who tickles their ears are the best pastors. It's no wonder such pastors always get to get luxury cars, some even have a private jet and are well-loved by the world but they're not men of God. John 15:18-19 and James 4:4 warns that friendship with the world makes one enemies with God. If you're a friend of God then you're an enemy of the world. Pastors who are popular are not right with God. Jeremiah 5:31 warns that people love false prophets and priests who bear rule by their means. Jeremiah 3:15 says that God will give pastors according to His own heart to replace all the condemned pastors who aren't according to His own heart.
The problem with worldly happiness is that it's fleeting compared to the joy that's the fruit of the Spirit. Holy happiness is absurd to the world. Matthew 5:11-12 would make any Christian look crazy to the unsaved because they're told to rejoice and be exceeding glad for their wrongful persecutions and accusations. The natural response is to get angry but Jesus told His followers to rejoice instead if they're ever wrongfully accused and wrongfully persecuted. God allows His children to suffer persecution as part of Christian growth. The truth is that a faith that's not tested can't be trusted. Do you want to have something that's not tested? You'd only want it after the test proves something is reliable.
The Christian life is a call for holiness. Only God is holy in the sense that only He is free from sin but the Christian is imputed with righteousness and holiness. 1 Peter 1:15-17 quotes from Leviticus 20:7 stating that Christians are called to holy living. A Christian's desire to be more holy than happy in the worldly sense. If anybody claims to be a believer but only cares about worldly happiness instead of growing in holiness then that person is really a false convert. A true Christian can be defeated for a moment by the cares of the world but the desire for holiness grows against it.
