Accurate information breeds confidence. Know what you believe. Disconnect from memories of past failures. Stop advertising your mistakes.
Remind yourself of good decisions and victories of the past. Before David fought Goliath, he mentally rehearsed past victories over the bear and the lion.
See yourself winning. Think and talk like the conqueror God intended you to be. Keep success pictures in your mind at all times. Remember, what you are goes before you.
“Nay, in all these things we are more than conquerors through him that loved us.”
“Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;”
(2 Corinthians 3:5)
