Churches, as described in the New Testament, are made up of people.
A church is not a building in which people meet, nor is it an organisation that people join, like a club. The churches established in the first century (Acts 14:23) were people who had obeyed the gospel and became disciples. (Acts 14:41)
The reason we claim to be the church of Christ is that, as closely as we can, we worship God the way he instructed the first Christians to serve him.
We start by listening to what He has to say and from that we come to realise we can trust Him and all His promises.
We are immersed in water to wash away our sins when we decide to live the way God wants us to.
Because God is a Spirit we need to worship Him as a spirit would. That means not just saying and doing things but by actually having those feelings in our heart. We need to demonstrate our love for God and our fellowman instead of just talking about it.
This takes time. We understand that we start like little children without much knowledge of what God wants from us but as we study and grow in our knowledge we become like adults and mature as Christians. This is what God
wants us to do.
This all happens as we read and study the bible and try to apply our new knowledge in our daily lives.
