For you have been called for this purpose, since Christ also suffered for you, leaving you an example, that you should follow in his steps. 1 Peter 2:21
Take these steps:
Renewing your Mind... daily
And do not be conformed to this world but be transformed by the renewing of your mind, that you may prove what the will of God is, that which is good and acceptable and perfect. Romans 12:2
Confessing God’s Word...daily
Death and life are in the power of the tongue, and those who love it will eat its fruit. Proverbs 18:21
Let your speech always be with grace, seasoned as it were, with salt so that you may know how you should respond to each other. Colossians 4:6
3. Letting God’s Word be in Every Thought
Let this mind be in you that was in Christ. Philippians 2:5
For though we walk in the flesh, we do not war against or according to the flesh, for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses. We are destroying speculations and every lofty thing raised up against the knowledge of God and we are taking every thought captive to the obedience of Christ and we are ready to punish all disobedience whenever your obedience is complete.
2 Corinthians 10:3-6
This third step is vitally important from the scriptures here in 2 Corinthians 10:3-6, because it tells us that we are in warfare and the daily solution against these conflicts are summed up in slowing our thinking down...taking every thought captive in order to respond as Jesus.
I have to say in closing, 90% of the problems we face are between our ears. Allow God’s word, be quickened by the Holy Spirit in your thought life to be able to talk in the “God Confidence” we need. Pray daily through these steps...I pray they help you because I live by them every second of every day.
