Likeminded by Henry Morris III, D.Min.
 

"Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind." (Philippians 2:2)

This emphatic command, along with the parallel terms, helps us understand the concept of "thinking" the same thing. "Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits" (Romans 12:16).

Such thinking also includes "having the same love." There are two aspects of this love. First, the term itself (agape) would demand that all of Christ's disciples "love one another: for love is of God" (1 John 4:7). This is often repeated to born-again believers so that our love for each other is so obvious that "by this shall all men know that ye are my disciples" (John 13:35).

Godly love then produces "being of one accord." This phrase is the translation of Greek word sumpsuchos, which is a compound of the preposition most often translated "with" and the word for "soul." Thus, the agape that we are to share results in a connection "with-soul" that binds the "likemindedness" in agreement with the mind and spirit of the Creator God.

We are finally commanded to be of "one mind"--slightly different than the "likeminded" opening charge of Philippians 2:2. The initial words are auto phroneô—"his thinking." The last use is en phroneô--one (way of) thinking.

The entire context of the opening verses of Philippians 2 is to think like Jesus Christ thinks. "Let this mind be in you which was in Christ Jesus" (Philippians 2:5). "Set your affection |phroneô| on things above, not on things on the earth" (Colossians 3:2). This kind of "thinking" must have God's love and soul embedded in the very core of our heart, soul, mind, and strength. HMM III
