Hell is selfishnesss and sin, far from God. Preaching about Hell often prompts fear, or else a kind of spirtual greed where a person wants the abundance of heaven instead of the deprivations of hell. It is hard to preach about hell in a balanced fashion that will help listeners.
Perfect love casts out fear. Teaching people about love is more heavenly. The holiness visible when someone sacrifices for another is a better encouragement for the indifferent than the threat of hellfire. It does not breed problematic fears and guilt.
Faith, hope, and love lead us out of our selfishness to a world that is closer to God. They turn us toward God.
