Christianity is about Christ, not people. People are deceived about all kinds of things. That's the human condition. Without continuous prayer, one can only drift into deception. I don't really understand how people walk away from Jesus (like go back to 'the world'). I always wonder if they ever met Him. And also, the only alternative to Christ is satan (he's the god of the world), so I'm even more confused when people 'leave Christianity'. Like,
where are you going??
I hold on to my faith by keeping my focus on Christ. Honestly, He's the one holding on to me because there have been times where I've felt like I can't go on, He keeps breathing life into me. He keeps filling me with His Spirit, encouraging me to hide His word in my heart and reminding me that the fear of the Lord is the beginning of wisdom. As long as I keep living for Him and walking with Him, He will keep me from falling (Jude 1:24-25). He'll do the same for all who come to Him.
Besides that, God has told us everything we need to know in His Word, the Bible:
2 Timothy 3:1-5 (NIV)
But mark this: There will be terrible times in the last days.
2 People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy,
3 without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good,
4 treacherous, rash, conceited, lovers of pleasure rather than lovers of God—
5 having a form of godliness but denying its power. Have nothing to do with such people.
This is where we are.
In my opinion if one is truly saved and is truly in Christ, the person is a work in progress. Yes, this includes racists. Everyone was saved from something. For various reasons, some people are still bound in alcoholism, some in racism, some in theft, jealously, pride, gossip, perversion, hatred, misogyny, new age practices, unforgiveness, witchcraft, lust, and on and on. If one has truly met the Lord of Glory and is committed to having Christ form His character in them, then they will eventually let all that go.
The trouble can be in distinguishing between Christians who are bound in some sin (racism in this case) and those who aren't Christians but think they are because they grew up in some kind of church setting. And a lot of professing Christians are Biblically illiterate. It's God's word that you know that changes you.
For me, I'm happy to walk away from people who are too proud to allow God's word to shape and (re)form them. That is where
I draw the line. If I know someone who is doing or believing XYZABC, and their friends or pastors or parents or whatever try to get them to give it up and go with God and they say no, that's someone I'm backing away from. I say that to say, if these so-called Christian nationalists have been corrected and remain unteachable and refuse to humble themselves under God's hand, well, I doubt their profession. I personally want to know if I'm dealing with ignorance or arrogance. Pride was the devil's first sin.
I don't know if that answered your question! Sorry if it didn't
How are you dealing with racism/Christian nationalism? Are you talking to Jesus about it? Take your frustrations to Him.
