“They don’t convert people by force. They try to convert people by reason.”
I think a simplier explanation than this is possible. The “conversion” of a person to “saving” belief in Jesus Christ is an act of God. It is God, in the person of the Holy Spirit, that brings this about. Belief or non-belief is between the individual and God. My only real function as a Christian in the “conversion” of others is to proclaim the message (as commanded in scripture) and then leave it in God’s hands to do the converting. “I” can’t “convert” anyone - only God can.
That’s exactly right. Only God can save. We can present but the Holy Spirit convicts them of the truth and their need for Christ.
