To speak against the sin while championing the sinner is an art. It is not easy.
IMHO, the trick isn’t to focus on the sin as much as to focus on Christ, and by faith, courage is intuitive to the mature believer. Homosexuality then simply becomes an aberrant way of thinking independent of God.
If we can give cause or example for any sinner to reconsider the thinking provided to us by Christ, they also will change their thinking, provided they simply rest in faith in Christ and what He provides.
I think too many confuse acknowledgement of His existence as a substitute for belief.
