The repetition of the truth of the gospel sponsors prompt obedience to God's word. As Christian believers, you should be sensitive enough to discern the words that are coming out of your mouth. Proverbs 18:2
If you want to see the manifestation of God's word then you have to embrace confessing God's word as a lifestyle that affects the way you think, speak, and the things you do.
What God desires of us as believers is that we are yielded vessels to his will, word, and ways for our life that submits to the authority of the Holy Spirit, and through that, we reflect the glory of God.
