"Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth." (3 John 2)
We prosper in our souls first, then we prosper in every other area of our lives.
John then explains the root of this prosperity:
"3For I rejoiced greatly,
when the brethren came and testified of the truth that is in thee, even as thou
walkest in the truth. 4I have no greater joy
than to hear that my children walk in truth." (3 John 3-4)
We are called to walk in the Truth.
The Truth is a person:
"6Jesus saith unto him, I
am the way, the truth, and the life: no man cometh unto the Father, but by me." (John 14: 6)
He is grace and truth personified:
"For the law was given
by Moses, but grace and truth came by Jesus Christ." (John 1: 17)
Grace and truth are met in Christ, who is the Living Word:
the beginning was the Word, and the Word was with God, and the Word was God." (John 1: 1)
Through the Word of God, we prosper:
"2But his delight
is in the law of the LORD; and in his law doth he meditate day and night." (Psalms 1: 1)
See Jesus in the Word, Let the Word off God lead you.
