The ritualist demands the outward, the conventional, the ancient usage of the past. Christ says, "Be natural." The needs of man, whether of body or of soul, are greater than ceremonial restriction. Ceremonies are only expressions of life, and where life is wanting, they are meaningless and void.
The withered hand, Mark 3:1-6. Through long disuse of powers which God has given, but which we have refrained from exercising, degeneration may have set in; Christ, however, bids us exert them again. In so far as we dare to obey, we shall find ourselves able. Dare to speak, or pray, or work, not at the impulse of your nature, but at His bidding, and you will suddenly find yourself given power.
The Apostolate, Mark 2:7-19. On three occasions Christ used the boat as His pulpit, Mark 4:1; Luke 5:3. We must be disciples (learners), before we can be apostles (those sent). As the Father sent the Master, so the Master sends us. Our mission is threefold-to bear Him company, to perform His errands, and to cast out devils. What infinite variety in the apostolic band! The Boanergic group of four; the group of questioners who were sometimes doubters; and the group of practical men, whose business capacity was a snare at least to one. If there was a traitor even amid the Twelve, who can expect to find his fields free from tares? [source]

Greek Commentary for Mark 3:15
To have power [ἔχειν ἐξουσίαν] Note that he does not say to preach and to cast out, but to preach and to have authority to cast out. The power of preaching and the power of exorcising were so different that special mention is made of the divine authority with which they would need to be clothed. The power of driving out demons was given that-they might apply it in confirmation of their teaching. Compare Mark 16:20. [source]
