I will build my church, and the gates of Hades will not overcome it. Mt 16:17
When Jesus speaks of the church, the first thing he tells us is that it is his. We forget this at our peril. It is so easy to forget that the Lord Jesus Christ is Lord of the church, that he bought it with his precious blood. As such, anything the church does must be in accordance with his word, so that his will may be done and that his name might be glorified.
When Jesus speaks of his church, he refers to the body of his people. Later in Mt 18, he speaks of the church speaking and hearing. Buildings don’t speak and hear, people do. This is the people redeemed by his blood, by faith, and who have received the Holy Spirit who enables them and works through them.
Also in Mt 18, Jesus speaks of the importance of a church to be holy, for its members to exercise self-discipline, and if they cannot, then they should be disciplined appropriately.
For where two or three come together in my name, there am I with them. Mt 18:20
Additionally, we are to meet together, expressing our membership of the universal church, by being committed to a local church. We are not to wander through our spiritual journey as hermits, but in fellowship with other believers. For the church is the kingdom of God on earth, our haven through which we may find support and encouragement.
As we live and work together in the church, if we holy then there will be harmony. We will love one another, just as our Lord loved us. This is not to say we will all be clones, but that we might be able to use our different distinctiveness’s in unity.
A church which does the will of her Lord will be a happy church. For in him we find our chief enjoyment.
