For years when I was a child, and I am 68 years old, people were saying Elvis Presley was a Christian because he sang gospel songs. He had no fruit of the Spirit and lived a wicked life.
An agonizing thing for a born again believer is for people to shout "don't judge" because we point out the truth, but the same people will judge someone as righteous without any evidence except a few songs or that someone attends a church gathering somewhere.
They are doing this same thing with our president and other prosperity preachers. They are not discerning because they are not reading their bibles and they are not consulting the Holy Spirit in prayer.
Matthew 7:21-23 "21 “Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter. 22 Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness.’"
The mantra today might be to God, "but Lord I told everyone I was a Christian"!
