God seldom intends that the Christian life should be a solitary one. It is first of all becoming reconciled to Him and then becoming His ambassadors beseeching others to be reconciled to Him.
2 Corinthians 5:20: Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ*s stead, be ye reconciled to God.
Paul wrote those instructions to a very carnal church so they are for ALL believers. Since He needs nothing from us, being reconciled to Him means loving Him, serving Him and beseeching others to do those same four things, be reconciled to Him, love Him, serve Him and beseech still others to do the same. My Pastor McBay once suggested that we look up the passages in the Bible that include the words one another.
John 13:34: A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
Romans 12:10: Be kindly affectioned one to another with brotherly love; in honour preferring one another; 13:8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. 14:13a Let us not therefore judge one another any more: . . . 15:7 Wherefore receive ye one another, as Christ also received us to the glory of God. 15:14 And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able also to admonish one another. 16:16 Salute one another with an holy kiss. The churches of Christ salute you.
1 Corinthians 16:20: All the brethren greet you. Greet ye one another with an holy kiss.
Galatians 5:13: For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. 5:26 Let us not be desirous of vain glory, provoking one another, envying one another. 6:2 Bear ye one another*s burdens, and so fulfil the law of Christ.
Ephesians 4:2: With all lowliness and meekness, with longsuffering, forbearing one another in love; 4:32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ*s sake hath forgiven you.
Colossians 3:13: Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye. 16 Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
1 Thessalonians 4:18: Wherefore comfort one another with these words. 5:11 Wherefore comfort yourselves together, and edify one another, even as also ye do.
Hebrews 3:13: But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin. 10:24 And let us consider one another to provoke unto love and to good works:
Galatians 6:10: As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith.
If you are not regularly part of a Biblical church, you are not doing any of these things for the household of faith. These things are called fellowship and ministering to the saints.
2 Corinthians 8:4: Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints.
