When I first came to the knowledge of the truth of Jesus Christ and the Holy Bible I didn't really understand all the denominations. But now that I have grown in faith and understanding of God's word, I realize that Satan is the one behind all the Christian denominations. Divide and conquer. What better way to separate Christians, what better way to make way for even greater divisions and heresies, what better way for Satan to infiltrate the Church than to divide it this way and that.
I do not claim any denomination. If asked what denomination I am. I am follower of Jesus Christ, I read the Bible and do exactly what God commands me to do. As should all that claim the Christian name. I often say to those who try to teach that you don't have to obey Jesus and can still be saved if you continue willfully in sin, I tell them that a Christian is not someone who merely believes in Jesus and His teachings but a Christian is someone who obeys Jesus and His teachings.
1 Corinthians 14:33 KJB
"For God is not the author of confusion, but of peace, as in all churches of the saints."
It is critically important that each and every one of us, especially in these last days (years) of the world, are in the Bible, reading and seeking God and His will, every day. For it is our spiritual food and without it we will starve and become unfruitful and distanced from the Lord. Not to mention the abundance of false Christians both in the churches, online and in our every day lives that are only sent to deceive us with their false examples and doctrines that teach things contrary to God's will. Such as you can live for yourself in pleasure, doing what you want and still be saved.
1 John 2:27 KJB
"But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him."
As far as denominations go, there is just different levels of hypocrisy and heresy you have to sift through until you realize that no matter what church you go to or whatever denomination you want to claim, there are innumerable agents of Satan in them all, ready to lead you astray if you let them. Be on guard. Study the word of God yourself. Don't let others convince you what doctrine is right. Read the holy word of God yourself and determine what is true yourself. Amen.
