3 Jn 1:2.
The prayer in 3 Jn 1:2 was for prosperity in all areas of life. You see it is God's will that we prosper in every area of life. God doesn't just want us to prosper in our spirits but not in our bodies or souls. In fact God's idea of prosperity goes beyond our spirits, souls and bodies.
The word prosper is loaded. It speaks of wholeness, and nothing missing, nothing broken. It encompasses every area of life. It is God's desire that we prosper in our families, careers, businesses, finances, etc.
When Jesus defeated the enemy, and rose up from the grave, He conquered sin, sickness and poverty - 2 Cor 5:21, 1 Pe 2:24 and 2 Cor 8:9. Jesus did all this for you and I; so that we could walk in victory and in the fullness of God's plan for our lives.
It is time for us to take our rightful place. Once you accept Jesus as your Lord and Savior, you have access to the blessing - Gal 3:13; you are no longer subject to the curse. The blessing is what truly makes a man to prosper - Pro 10:22. The stage has already been set for you. Go forth and prosper in all things.
