"Let this mind be in you, which was also in Christ Jesus." (Philippians 2:5)
Although salvation is free, it is not cheap, since it required the Creator Himself to become man and submit to an agonizing death on the cross. This was the mind of Christ!
And, by the same token, although our salvation is not conditioned on any meritorious acts of our own, the standard by which we must measure our lives is nothing less than the perfect life of Jesus Christ. In the first place, our words and deeds are to be compared to His: "For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps" (1 Peter 2:21). Our standard of holiness is to be His life of holiness. "But as he which hath called you is holy, so be ye holy in all manner of conversation |meaning 'behavior'|" (1 Peter 1:15).
If we truly follow His steps, they may well lead to suffering and persecution, but "he that saith he abideth in him ought himself also so to walk, even as he walked" (1 John 2:6), and this involves a willingness to be "crucified with Christ" (Galatians 2:20). The Christian life is pre-eminently to be characterized by unselfish love, but again the standard of that love is nothing less than the love of Christ Himself. "A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another" (John 13:34).
To love as He loved; to walk where He walked; to be holy as He is holy; to follow His example in word and deed--all this requires that we think as He thought, that the very attitude of our soul be like His. In position, we do "have the mind of Christ" (1 Corinthians 2:16), but in practice, we still come far short. May God help us to cast down "imaginations, and every high thing that exalteth itself against the knowledge of God," and bring "into captivity every thought to the obedience of Christ" (2 Corinthians 10:5).
