Let me begin by saying our spirit (heart) is constantly exposed to God’s Spirit, because at new-birth experience, it becomes one with the Holy Spirit. 1 Corinthians 6:17 says, “But he that is joined unto the Lord is one spirit.” Our spirit is our innermost being. Our spirit is quickened in the Holy Ghost when we sincerely give our life to Jesus Christ.
Whereas our mind still continues to have contact with this present wicked world. No matter how repented we have been and how holy our heart has become, our mind will still continue to have romance with this world, through our physical senses (tasting, smelling, touching, seeing and hearing), which have direct contact with the physical world.
This is the reason why we must take the renewal of our mind very very serious. We must give it all it takes, as long as we remain in this mortal body, even by the help of the Holy Spirit. For without the Holy Spirit we can do nothing.
Now if we give up renewing our mind every time, we stand the danger of falling into our old sinful way and life, even with our regenerated heart (the new spirit given us).
Here is even the main danger: if we don’t still get our mind renewed, we will come into a place, where sin will begin to serve as cancer, spreading from our mind to our heart, which has become new in Christ Jesus. And as this continues, there may or will come a time when our heart will become so bad, that we will begin to make expensive wrong choices again. And since God always respects every man’s choice, we may happen to make a wrong choice that will cost us eternal life with God, and not repent or even get a chance to, turn back from it until death catches up with us. (God forbid we end up in hell.)
And since God is called the “I AM THAT I AM,” meaning, He is the God of now, and not of the past, nor future. He doesn’t have past, nor future, but only now. Then it means, it is the present choice, which we have made, that we will be judged upon. Then shall Ezekiel 33:13 and 18 be fulfilled, which says,
“When I (God) shall say to the righteous, that he shall surely live; if he trust to his own righteousness, and commit iniquity, all his righteousness shall not be remembered; but for his iniquity that he hath committed, he shall die for it.”
“When the righteous turneth from his righteousness, and commit iniquity, he shall even die thereby.”
Ephesians 5:5-6 says,
“For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. Let no man deceive you with vain words: for because of these things comes the wrath of God upon the children of disobedience.”
This is why it is possible for somebody that is saved today to wind up in hell tomorrow. In 1 Corinthians 9:27, Apostle Paul says, ” But I keep under my body, and bring it into subjection: lest by any means, when I have preached to others, I myself should be a cast away.”
And that is why Jesus Christ said, we have to deny ourselves, carry our cross and then daily follow Him, Luke 9:23.
And how do we follow Jesus? We follow Him by following His mind that we have received in us. 1 Corinthians 2:16 says, “… But we have the mind of Christ.” And this mind of Christ can only be properly effective when we have the Word of God abiding in us. “Thy Word have I hid in mine heart, that I might not sin against Thee,” Psalms 119:11.
O God, help me remain in You to the very end. Let the Mind of Jesus overrule in me always. In Jesus’ Name. Amen.
