Why look down on fellow Christians?
Romans 14:4
Rom 14:4 Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
When that servant shows up on a public forum and claims that we are under the law, or that God's scripture is wrong or not enough; that Christians are not indwelt with the same Holy Spirit that a pope claims to have guiding him, and that his is the only true religion, then God expects us to stand up and shout...Shout to proclaim the biblical truth...
When God says there will be no signs given yet a religion comes up with signs and wonders to sway people to believe that their religion, which is contrary to scripture, is the true religion, then we are obligated to correct them with God's scripture...
