God uses different Christians in different ways. Some are powerful preachers, others can help the poor, yet others see are very good at praying while another person may possess gifts of leadership and administration. You and I thus have important functions in this world. We are not to be jealous or envious of one another but to build one another up in love - just as in our human body the arms acre for the head etc. We are to be a team.
Much hurt can come when Christians compete with one another.
Sound biblical preaching that lifts up Jesus Christ as Saviour, Lord and God. Humble , godly and wise leadership. The people of the church clearly love one another. There is holiness and clear standards of right and wrong. If you are unsure about a church then talk to some wise Christians that you know and ask their opinion of it.
