"The mind of sinful man is death, but the mind controlled by the Spirit is life and peace; because the sinful mind is hostile to God. It does not submit to God's law, nor can it do so. Those controlled by the sinful nature cannot please God".
"You, however, are controlled not by the sinful nature but by the
Spirit, if the Spirit of God lives in you. And if anyone does not have
the Spirit of Christ, he does not belong to Christ. But if Christ is in
you, your body is dead because of sin, yet your spirit is alive because of righteousness".
Praise God! This is a promise from God Himself to us! We are already have what it takes to be controlled by the Spirit because it is God Himself living in us! Our spirit is alive BECAUSE of righteousness, we ALREADY have a right standing with God! HALLELUJAH! Then, to throw any doubt out, God goes on to say:
"And if the same Spirit of him who raised Jesus from the dead is
living in you, He (the Spirit) who raised Christ from the dead will
also give life to your mortal bodies through his Spirit, who lives in you".
Praise your Holy name God!
We have just discovered a truth that will sustain and keep us free of negative thoughts if we so choose it to do so! But HOW
do we do it? We do it according to Romans 13:14 which states:
"Rather, clothe yourselves with the Lord Jesus Christ, and do not
think about how to gratify the desires of the sinful nature."
In other words, decide to put on the mind of Christ and refuse to think about anything that attempts to get you to resurrect your old sinful nature!
