“Be kindly affectioned one to another with brotherly love; in honour preferring one another;” (Romans 12:10)
An attitude of love and concern should prevail in any Christian assembly. This commandment does not absolve a man of his responsibility to consistently show love when the other is being unlovely. When others do not reciprocate love, the power of the Holy Spirit may be truly put to the test in the believer's life. The Spirit will not fail, but often times the believer chooses to gratify his own flesh through revenge or bitterness. Such a course of action finds no place in this passage, or in the rest of Scripture. The last phrase has the meaning of honoring others above one's own self. When a man chooses to make the needs of others more important than his own, he is truly emanating the character of Jesus Christ, “For even the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many (Mark 10:45).”
“Not slothful in business; fervent in spirit; serving the Lord;” (Romans 12:11)
The word for business is the same word translated diligence in verse eight. Laziness is often glorified or passed over as an “insignificant issue,” but God considers it to be sin. He has entrusted every believer with a certain amount of business, and He expects His people to make full use of it. To squander one's own time, money, and resources is to rob God. The word fervent means to glow or burn brightly. The Spirit of God desires to shine through the believer in a very real way, but He can be quenched by sinful choices and desires (I Thessalonians 5:19). The last phrase reveals the secret to a consistently vibrant Christian life. The secret is serving the Lord. Some Christians serve themselves, some serve their emotions, some serve their pastors, some serve a prominent teacher or speaker, and others serve a host of various masters; but the one who serves the Lord will be consistent to the end.
