Many people live in a strong delusion secretly following Christ yet deny him publicly. These people claim to be wholly resting upon Jesus Christ for salvation, while at the same time trying to please the world. This is so typical of deception and lies. Most people who profess to know God do not know God at all. They are double-minded who believe in Christ with lukewarmness in their heart and constantly living in a state of compromise. A double-minded person is one who says one thing and do another, they claim to know God and yet their actions do not live up to such claims. God's Word says that a double-minded man is "unstable in all he does." (James 1:8).
The true Spirit-led Christian is not going into compromise their fire and love for God. Matthew 6:24 says No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
Exodus 34:14 says Our God is a jealous God and will not accept a service that is divided with Satan. Because those who serve two masters are unsteady, hypocritical, double minded, wavering in both character and feelings and is always conflict to himself. They are not true believers in Christ and they have very nature of carnal mind and have cowardness which is enmity against God . They can not express the word of God truthfully without fear. Their lifestyles separate because of backsliding. Proverbs 14:14 says, "The backslider in heart shall be filled with his own ways. Jesus also expects us to preach the Gospel, which offends most false professed believers.
To deny Jesus Christ is to deny God's Holy Spirit. 1st John 1:22,23 plainly state "Who is a liar but he that denieth that Jesus is the Christ? He is antichrist that denieth the Father and the Son. Whosoever denieth the Son, the same hath not the Father ..but he that acknowledgeth the Son hath the Father also."
2 Timothy 3:5 says they have a form of godliness, but denying the power thereof from such turn away.
Conclusion: Anyone who is in Christ, they live for him alone and are obedience to Him. If we worship God in spirit and in truth, we cannot worship anyone or anything else (Matthew 4:10).
