You are either a Christian or you are not a Christian; You cannot be partially a Christian. ~ Martin Lloyd-Jones
Do you change your attitude about Christianity depending on who you are talking to? If you choose to be a Christian, then it is essential that you maintain Christ-like qualities and attitudes in all aspects of your life.
Don’t be ashamed to be a follower of Christ. He is there to support you, and you need to be the light that should be shared with other people around you.
