Romans 10:8-10 8 But what does it
say? “The word is near you,
in your mouth and in your heart”
 (that is, the word of faith which we preach): 9 that if you confess with your mouth the Lord Jesus and believe in your
heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth
confession is made unto salvation.
What we believe is a result of our thinking. If we think wrong, we will believe wrong. If our believing is wrong, our confession is wrong. In other words, what we say will be wrong. But the Word of God has been given to us to straighten out our thinking!
Ordinarily, we talk quite a bit about the believing part, but we do not talk too much about the saying part. Of course, we will not be
able to make the right confession until our thinking is right. Our thinking must be in line with the Word of God, because we cannot believe beyond the
actual knowledge we have of the Word of God.
For example, the Bible says, “Trust in the Lord with all your heart; and lean not on your own understanding (MIND)” Proverbs 3:5 The Bible says, “Casting down imaginations(REASONINGS), and every high thing that exalts itself against the knowledge of God, and bringing into captivity every thought (THINKING) to the obedience of Christ; 2 cor. 10:5. The Bible also says, “And be not conformed to this world: but be transformed by the renewing of you MIND, that you may prove what is good, and acceptable, and perfect will of God.”
Romans 12:2
We renew our minds by studying the Word of God. The Bible teaches us to have the mind of
Christ. The only way we can have the mind of Christ is to study His Word,
believe it in our heart, and act upon it. Of course it is also important to care for your health. A healthy body is a very important thing in order to do everything listed here. I for example take a health supplement that has been working really well for me. It is natural, safe, and very effective. I highly recommend it. You can go here to Learn More About It.
