Listen as we consider how when Jesus began to preach He immediately began to disciple men, and how different the qualifications are for ministry than we might first assume. We also see how Jesus was sovereign over the choosing of the right men for what would follow, including the selection of Judas to be His betrayer.
Where Christ and His work are exalted, and where that love is known and experienced, it is freely given and you know you are in a faithful church. Out of that knowledge of Christ and His Word, the character and work of the church flow. In a faithful church, with faithful teaching and obedience, one of the key distinctions that will be visible on the inside and outside is unity.
