" God is saying when you stay full of joy, when you learn to offer up the sacrifice of praise, God will turn things in your favor. He will reverse negative situations. He will return, or restore, what’s been stolen.
But notice that restoration doesn’t come from complaining, being negative, or being sour. Restoration takes place when you have the voice of gladness, the voice of joy. That means you get up in the morning with a song in your heart. You go out each day with a smile on your face. Things may not always go your way, but you don’t become discouraged. You shake it off and count it all joy.
When you live that way, you might as well get ready. God will be reversing and restoring. He will reverse finances that have been down. He will reverse a struggling business. He will reverse a legal situation in your favor. He will reverse a health issue to heal you.
Not only that, God will restore what should have been yours. He will restore the years you lost because somebody did you wrong. He will restore a relationship that’s on the rocks. Restoration will occur because you have the voice of joy, the voice of gladness, and you keep offering up that sacrifice of praise.
Learn to count it all joy. Don’t be determined to never have problems. Be determined to stay full of joy in the midst of your problems. Arrange your mind in the right direction.
And no matter what comes your way, don’t lose your joy. Learn to offer up that sacrifice of praise. If you keep the voice of gladness, the voice of joy, you cannot stay down and defeated. God has promised He will reverse and restore. Not only that, but because you have joy, you will find the strength to outlast every attack, to overcome every obstacle, to defeat every enemy. You will become everything God created you to be, and you will have everything God intended for you to have. "
