Jesus gave authority to His disciples (1). He gives authority to us. It is the authority of the Word and the Spirit – ‘you will be given what to say’ by ‘the Spirit of your Father speaking through you’ (20). Christ’s disciples were being trained for a great work to be done in the Name and the Power of the Lord (28: 18-20). If we are to communicate the Word in the power of the Spirit, we need to see our life as life in the Spirit and life under the Word. Scripture calls us to ‘be filled with the Spirit’ (Ephesians 5:18) and to ‘let the Word of Christ dwell in us richly’ (Colossians 3:16). To be filled with the Spirit is to let the Word of Christ dwell in us richly. To let the Word of Christ dwell in us richly is to be filled with the Spirit. We are to live in the power of the Spirit. We are to live in accordance with the Scriptures.
