Bible truth is the basis for orientation to God's plan during the believer's lifetime. Trust in the Lord forever, for in God the Lord, we have an everlasting rock. Bible knowledge produces sanity and stability of mind. It is very important to get the Word of God into the mind before the times of pressure come. It is not too likely that an unstable person will respond to the Word of God.
Bible truth is the basis for divine guidance.
With all believers in a local church being guided by the same truth, there will be unity. 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. But without the Word of God, the believer's mind will be corrupted by Satan and will become a repository of world-viewpoint and false teaching. But I am afraid, lest as the serpent deceived Eve by his craftiness, your minds should be led astray from the simplicity and purity of devotion to Christ. This is avoided by the process outlined in verse 14.
