That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation (Romans 10:9-10).
It’s not enough to know the Word of God in your heart; you have to speak it forth as well—that’s how it works! God instructed Joshua, “This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success” (Joshua 1:8). The original Hebrew rendering of the word “meditate” is “hagah,” which means to ponder, roar, imagine, murmur, mutter, speak, talk, or utter. It’s much more than thinking the Word; you have to voice it!
The opening verse shows us that speaking out what you believe is a fundamental spiritual principle without which the gift of salvation can’t be received. The salvation package is delivered upon satisfying two conditions: the first is “believing,” while the second is the “confession” of that which you’ve believed. Both work together for salvation to be complete.
In the same way, to live the glorious life in Christ, where you enjoy all the benefits of salvation, you must keep the Word in your mouth always. You must believe and speak. Some people find themselves in unpleasant situations and say, “I believe the Word of God, but I don’t know why things aren’t working out right for me.” Believing the Word alone will not change anything, until you start using your mouth right, by speaking what you believe.
Your mouth was given to you to create your future and your victorious life. Your life goes in the direction of your confession. You have to say what you want in life. Even now, speak the Word about your family, job, business, academics, health, etc. Release the dynamic power to effect the changes you desire by speaking forth faith-filled words.
