I fear such things happen primarily because “soulwinners” do their thing their way, produce “decisions” rather than converts, and, even if the salvation is Spirit-born, the “soulwinner” then trucks off to score more “decisions” and leaves the new-born child of God on his own.
The contemporary “evangelist” all-too-often makes “decisions” for Christ easy (heads bowed, eyes closed, raise your hand etc). Contrast that with the gospels, where, at least in my reading, Jesus always made it easier to say “no” than to say “yes.”
Are invitations bad? Not at all.
But when there is no focus on the horribleness of our sin, the need for repentance, and the radical-ness of following Christ in obedience, there will be simply more spiritual meteorites…rather than growing disciples of our Lord Jesus Christ.
