1- Does the church affirm the teaching of Scripture? Is Scripture alone its authority for matters of life and faith or does the Bible only have a small influence on what its leaders teach?
2- Does the church believe in the deity of Jesus, that Jesus is God, and that Jesus’ death in our place on the Cross is the only thing that can save us, making us right with God?
3- Does the church believe that in order to receive that salvation, a person must repent from sin and put his or her trust in the person of Jesus Christ?
4- Do its leaders demonstrate spiritual leadership, maturity in their faith, and the fruit of the Holy Spirit?
5- Will I be able to use my spiritual gifts and thrive in my walk with God?
No two churches are alike. Some churches will differ in matters of worship, style, community impact, denominational convictions, global mission, dress, etc. Most of these are matters of preference after you have ensured that the foundation of the church is biblically sound.
