2 Timothy 3:5-7
5 Having a form of godliness, but denying the power thereof: from such turn away.
6 For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts,
7 Ever learning, and never able to come to the knowledge of the truth.
You will come across those who claim to be Christians. They will talk to you about church and how they love the Lord. However, you find that they do not live the life. They want the title of Christian, but they do not want to put in the work of a Christian. Be careful about these people. Some you can reach, but others have convinced themselves that they are perfectly fine. They do not realize that you have to have Christ in your life. The best thing to do is pray that God opens their eyes.
