Self-Confidence will blind you
“For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ.” 1 Corinthians 12:12
“In the apostles’ day there were some misguided souls who claimed to believe in Christ, yet refused to show respect to His ambassadors. They declared that they followed no human teacher, but were taught directly by Christ without the aid of the ministers of the gospel. They were independent in spirit and unwilling to submit to the voice of the church. Such men were in grave danger of being deceived.” The Acts of the Apostles 278.4
“God has placed in the church, as His appointed helpers, men of varied talents, that through the combined wisdom of many the mind of the Spirit may be met. Men who move in accordance with their own strong traits of character, refusing to yoke up with others who have had a long experience in the work of God, will become blinded by self-confidence, unable to discern between the false and the true. It is not safe for such ones to be chosen as leaders in the church; for they would follow their own judgment and plans, regardless of the judgment of their brethren. It is easy for the enemy to work through those who, themselves needing counsel at every step, undertake the guardianship of souls in their own strength, without having learned the lowliness of Christ.
Impressions alone are not a safe guide to duty. The enemy often persuades men to believe that it is God who is guiding them, when in reality they are following only human impulse. But if we watch carefully, and take counsel with our brethren, we shall be given an understanding of the Lord’s will; for the promise is, “The meek will He guide in judgment: and the meek will He teach His way.” Psalm 25:9. The Acts of the Apostles 279.1, 2
