Discipleship 101

Why did the LORD choose 12 Apostles? How is prayer casting yourself entirely on the LORD? Did anyone take Christ’s life from Him in His death on the cross? Is everything in Salvation determined by the LORD including the ‘where’ the ‘when’ and the ‘how’? Why did Jesus tell the disciples not to rejoice in the fact that the devils were subject to them? What did Christ mean by saying His disciples were like lambs among wolves? Why do the wolves attack Christ’s lambs as they did Him?
