Whether one member suffer, all the members suffer with it; or one member be honoured, all the members rejoice with it. 1 Corinthians 12:26. RRe 156.1
Christianity is a system, which, received and obeyed, would spread peace, harmony, and happiness throughout the earth. The religion of Christ will unite in close brotherhood all who accept its teachings. It was the mission of Jesus to reconcile men to God, and thus to one another.—The Great Controversy, 47. RRe 156.2
Let your hearts be true to Jesus. Although you may feel that you are the least of all saints, yet you are members of Christ’s body, and through Him you are identified with all His human agencies, and with the excellence and power of the heavenly intelligences. None of us liveth to himself. To each is assigned a post of duty, not for his own narrow, selfish interests, but that the influence of each may be a strength to all.—Testimonies for the Church 7:296. RRe 156.3
God’s church is the court of holy life, filled with varied gifts, and endowed with the Holy Spirit. The members are to find their happiness in the happiness of those whom they help and bless.—The Acts of the Apostles, 12. RRe 156.4
