Jesus said to him, “I am the way, and the truth, and the life; no one comes to the Father but through Me.” - John 14:6 New American Standard Bible (NASB)
I was involved in the “ex-gay” movement for almost 21 years. While rare, there is an argument I have encountered saying that a person’s response to homosexuality is the litmus test of whether someone is truly applying The Gospel or even saved.
Every time I hear this it gives me chills. The truth is that if there actually is a litmus test, that test is Jesus Himself. To put anything else in place of Him as being the singular evidence of salvation, The Good News (Gospel), is simply idolatry by a different route.
