It should not surprise us, as Paul wrote in 2 Corinthians 11:13-15:
13 For such men are false apostles, deceitful workmen, masquerading as apostles of Christ. 14 And no wonder, for Satan himself masquerades as an angel of light. 15 It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve.
As Christ Himself taught, as well as His disciples, there would be many who would teach falsely, but only one "narrow path" that led to truth, so we are to discern by fruits (the fruits of the Holy Spirit) which "Christians" are true, and which are false, and build our spirituality upon rock, truth, faith (Matthew 7:13-27):
The Narrow and Wide Gates
13 "Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. 14 But small is the gate and narrow the road that leads to life, and only a few find it.
A Tree and Its Fruit
15 "Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves. 16 By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles? 17 Likewise every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus, by their fruit you will recognize them.
21 "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven. 22 Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name, and in your name drive out demons and perform many miracles?' 23 Then I will tell them plainly, 'I never knew you. Away from me, you evildoers!'
The Wise and Foolish Builders
24 "Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash."
It should not surprise us, as Paul wrote in 2 Corinthians 11:13-15:
13 For such men are false apostles, deceitful workmen, masquerading as apostles of Christ. 14 And no wonder, for Satan himself masquerades as an angel of light. 15 It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve.
Real faith must be placed in God, through Christ, not men (organized religion). Develop faith in Him through daily heartfelt prayer, Bible Study, and practicing the Fruits of the Holy Spirit, and doing His will, and you will find your way to the narrow path, avoiding the confusion caused by manmade religion.
