Jesus gave His disciples the power to cast out demons and to perform miracles of healing (Matt. 10:8). He gave them His authority to minister to people, yet they became so self-centered that they lost the power to do the work of God. When God sent a father with his epileptic son to them for healing, they failed miserably. They were so concerned with position and status (Mark 9:32-35) that they lost their focus on what God wanted to do through them.
Jesus’ response to His disciples included some of the harshest words ever to come from His mouth. He called His own disciples “unbelieving” and “perverse” and questioned how much longer He had to endure them! Why? Because they were supposed to be on mission with Him to bring salvation to others, but they had become so disoriented to Him that they were spiritually powerless, lacking the faith to bring physical and spiritual comfort to those God had sent to them.
God ought to be able to send a hurting person to any child of His and expect that they will be helped. Like the disciples, we can become so preoccupied with our own ambitions and distracted by the busyness of our lives that we become ineffective in ministering to those whom God sends to us. It is even possible to become so involved in religious activity that we are of no help to anyone. Regularly take inventory of your life to see if you are being a faithful steward of every life God sends to you.
