Jesus’ words, "Feed my lambs" (John 21:15) are a commission for all His followers. Those who take their commission seriously and teach children at church are working hand-in-hand with God. The apostle Paul may have been thinking of spiritual educators when he admonished Timothy: "Study to show thyself approved unto God, a workman who need not be ashamed." (2 Timothy 2:15)
With this in mind, the North American Division Children's Ministry has developed a series of certifications to help teachers,leaders and children become more effective and competent in their work for God's kingdom. These certifications can be completed by attending training online or attending a Go Fish Training.
