Beware of what you think and speak!

Do not often dwell on the negative thinking, what you fear most might be made use of by the devil and be used against you.
Think twice before you speak, least you be controlled by what you said.

2Thou art snared with the words of thy mouth, thou art taken with the words of thy mouth. Proverbs 6

We are set free by the dead of Jesus Christ, so that we are free to do what we want.

1Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
Galatians 5

Faith is not relying on the circumstances or our feeling, It is holding steadfastly on the words of God.
