Are you a good debater, have you deep understanding of Christian theology, have you the means to reach these lukewarm christians and convince them to change/repent?
If not you have two options.
1/ to live as a devoted Christian, witnessing Jesus’s love to those around you while supporting a church that teaches Christ.
2/ to pray for these lukewarm Christian by name.
