How does a sincere person find the right God and the right house? They take the Word of God and use it as the evidence of God’s presence. Let me make this very simple. I will give you a Scripture spoken by Jesus, if men believe it they will not be ashamed to proclaim it.
Mark 16:17-18 And these signs shall follow them that believe; in My Name they shall cast out devils: they shall speak in new tongues. They shall take up serpents: and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick and the sick will recover.
If anyone will present this Scripture to a church, they will quickly know if God is in that house or not. If the pastor tries to explain away this Scripture and try to tell you that the day of miracles have passed, then you would be wise to pass. If the pastor pleads guilty to believing the words of Christ you may have found a home to grow in.
No church is perfect but some can be so imperfect they are not worth your time or effort. None of us are called to go around and correct every ministry, but we are encouraged to check out the fruit. Every good tree produces good fruit and every bad tree kicks out bad fruit.
