Jesus Christ told us in His Word, the Bible that in the end times, the church would be apostate teaching false doctrines and will act as described in 2 Timothy 3:1-5
2 Timothy 3:1-5
Difficult (ragingly insane, in the original language) Times Will Come
3 But realize this, that in the last days difficult times will come. 2 For people will be lovers of self, lovers of money, boastful, arrogant, slanderers, disobedient to parents, ungrateful, unholy, 3 unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good, 4 treacherous, reckless, conceited, lovers of pleasure rather than lovers of God, 5 holding to a form of godliness although they have denied its power; avoid such people as these.
Only those who have been changed into a new creation by Christ will be different from this terrible world. There are lots of pretenders who say they are Christians but have never trusted in Christ, they are only using His name for their own advantage. When Christ changes us we have a completely different spirit and that is the Holy Spirit of Christ.
When He has changed us we have His fruit:
Galatians 5:22-23 " 22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, and self-control. Against such things, there is no law.…"
Matthew 7:21-23 describes the pretenders:
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. 22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ 23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’"
Even the seculars are noticing the increase in mean-spirited rudeness that dwells everywhere all the time. People tend to only be kind and happy when they are being personally praised or elevated. They do good deeds but to magnify themselves.
Born again believers do good deeds but do not advertise it as the unsaved do. Believers love to honor Christ in their deeds and have no need or desire for anyone to notice.
Only those who are born again can discern the difference between the saved and the unsaved. They do not judge who goes to heaven or hell because some of those unsaved may trust in Christ before they die, but they can see what is what in the present.
Matthew 7:15-20
You Will Know Them by Their Fruit
15 “Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. 16 You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? 17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore by their fruits you will know them."
What is this fruit? Here is what God said, as stated previously in this article;
Galatians 5:22-23 " 22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, and self-control. Against such things, there is no law.…"
