21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven” Matthew 7:21-23

So often I get this response but I’m happy to answer your question, No - It takes more than just a “call out” to be saved. But it is the first step and there are several after that. To be truly saved you must truly repent - meaning you are truly sorry for what you did and make every intention of not committing that sin again. It can take years of prayers if not a lifetime to overcome a very grave sin - only God knows your heart and whether you truly repented or not. But if you do not repent even the smallest sin can send you into eternal hell. We are all sinners, some bigger than others. Those you describe are so far from God that they will never surrender - this is why they need our prayers. Imagine what God can do with someone like that who once worked for evil but now surrendered their life to Him? I would image he at least could use them to expose the rest. So yes pray for your brothers and sisters who have sold themselves to evil. Many will not turn around but we only need a few of them on our side to start flipping tables.
