14 Do not be unequally yoked with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? 15 Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? 2 Corinthians 6:14-15 (LSB)
Contrary to what most believe about Christianity, what one’s own framework is of their conception of salvation and having fellowship with Jesus Christ is irrelevant. Unless this ‘understanding’ is totally submitted to the Word of God and the authority of God the Father, God the Son, and God the Holy Spirit then it will be according to the counsel of the individual’s own conscience. This counsel is according to the value system of the individual not according to what God has revealed. It creates its own image of God and holds that image accountable to the individual’s value system.
Our whole Salvation consists only in Christ. Those who are ‘saved’ have been redeemed from the slave market of iniquity and been declared righteous according to the righteousness of the Saviour. However, the redeemed are not perfect and still sin. What many who have their own unbiblical concept of our salvation believe is that all we really need to do about our sin is feel bad, make a fuss about it, and promise God that we will try harder next time to abstain. These same professing Christians will cry foul and resist any teaching that calls for the mortification of our sin saying that that is only fodder for self-righteousness.
