It takes Positive to keep the faith yet, some negative is needed. The negative things we think  in the Spirit is a trial the trials only come to make us stong and teach us how to endure. Even in a trial we must think positive and give Almighty God glory, prais, and worship. Philippians 4:8  “Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.”

King James Version (KJV)
