What is God's idea of true unity? Not everyone sees truth the same way. Not all words mean the same thing to every person. For this reason, God's plan is to bring a variety of backgrounds, personalities and diverse minds to His vineyard, so that all nations, kindred, tongues and peoples will be reached. Sometimes we think because a person does not word the Gospel in the exact same way we do, it is suspect of being a false gospel. Here are some EGW comments to think about.
Unity in Diversity
God's Plan in a Diversity of Gifts.--In all the Lord's arrangements, there is nothing more beautiful than His plan of giving to men and women a diversity of gifts. The church is His garden, adorned with a variety of trees, plants, and flowers. He does not expect the hyssop to assume the proportions of the cedar, nor the olive to reach the height of the stately palm. Many have received but a limited religious and intellectual training, but God has a work for this class to do if they will labor in humility, trusting in Him.--Letter 122, 1902. {Ev 98.3}
Characters as Varied as the Flowers.--From the endless variety of plants and flowers, we may learn an important lesson. All blossoms are not the same in form or color. Some possess healing virtues. Some are always fragrant. There are professing Christians who think it their duty to make every Christian like themselves. This is man's plan, not the plan of God. In the church of God there is room for characters as varied as are the flowers in a garden. In His spiritual garden there are many varieties of flowers.--Letter 95, 1902. {Ev 99.1}
Diverse in Mind and Ideas.--Diverse in mind, in ideas, one subject is to bind heart to heart--the conversion of souls to the truth, which draws all to the cross.--Letter 31, 1892. {Ev 99.2}
Special Talents for Special Work.--One worker may be a ready speaker; another a ready writer; another may have the gift of sincere, earnest, fervent prayer; another the gift of singing; another may have special power to explain the Word of God with clearness. And each gift is to become a power for God, because He works with the laborer. To one God gives the word of wisdom, to another knowledge, to another faith; but all are to work under the same Head. The diversity of gifts leads to a diversity of operations; but "it is the same God which worketh all in all." 1 Cor. 12:6. {Ev 99.3}
The Lord desires His chosen servants to learn how to unite together in harmonious effort. It may seem to some that the contrast between their gifts and the gifts of a fellow laborer is too great to allow them to unite in harmonious effort; but when they remember that there are varied minds to be reached, and that some will reject the truth as it is presented by one laborer, only to open their hearts to God's truth as it is presented in a different manner by another laborer, they will hopefully endeavor to labor together in unity. Their talents, however diverse, may all be under the control of the same Spirit. In every word and act, kindness and love will be revealed; and as each worker fills his appointed place faithfully, the prayer of Christ for the unity of His followers will be answered, and the world will know that these are His disciples. . . . {Ev 99.4}
