What priority does the “conversion experience” play in modern forms of Christianity?

Conversion experience is something that one goes through once in their lifetime. It is that moment when one accepts Christ Jesus as their Lord and Savior, repenting of their sin, asking Christ to forgive that person and cleanse them. It is a spiritual turning point that involves transformation within. The specific conversion is a point in time event, not an on-going lifetime event. Transformation does continue throughout one's lifetime after conversion.

If one has not been "converted".. which ONLY God can do... then one can not become a True Christian... however... just because God "converts" someone... does not mean that God compels any one to submit to Him.... God will not impose His Word and Will upon anyone not already in willing submission to Him..... and no one of The True Church commissioned by God should ever try to do that either....

FYI... There is ONLY One True Church commissioned by God... and The Body of The True Church consists of ALL those of The True Christian Faith.... and ONLY God decrees who is of The True Church

Conversion is a process that all Christians go through until the day they die.
