It really dosn't matter who belives it. It matters whether or not you believe it. What does the Bible say? What does your mind and heart say?
Jeremiah 6:16 "Thus saith the LORD, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But they said, We will not walk therein."
(KJV)
Philippians 4:6 "In nothing be anxious; but in everything by prayer and supplication with thanksgiving let your requests be made known unto God.
7 And the peace of God, which passeth all understanding, shall guard your hearts and your thoughts in Christ Jesus."
