As the story goes, Bill Gates was sitting in a university classroom when he was hit with a technological inspiration -- what resulted is Microsoft. General Booth was captured with a desire to form a religious organization to take care of the poor -- what resulted was the Salvation Army. D.L. Moody became burdened for orphaned and latch-key kids -- what resulted was the YMCA.
God had a plan for His church. As thousands of people responded to the message of the gospel, success brought obstacles. The early church became strained with the pressure to meet people's needs without favoritism. God had a ready response in mind; the church would choose men filled with the Spirit of God and the wisdom that comes with that filling. Those men would sift through the needs, help restore unity, and broaden the work of the church.
It was important that those called to preach/teach God's Word, and spearhead prayer (godly leadership) not be deterred from doing so. Fast forwarding two thousand years, my place in the body is to lead in similar fashion as the original twelve at Jerusalem. In God's economy, deacons fill a vital role for me to do so, and for the church to remain healthy. When Paul wrote to the church at Philippi, he began his letter with these words:
To all the saints in Christ Jesus at Philippi, together with the overseers and deacons: Grace and peace to you from God our Father and the Lord Jesus Christ. (Philippi 1:1-2)
The office of a deacon is not a result of the brilliant inspiration of men. Deacons are men who have responded to one of the purposes for which they were created -- helping saints and overseers keep it together in a Christ honoring fashion.
