Agreements on construction should be obtained in writing, not verbally. This puts the church in a much more secure position. Christians then need to present a good witness to the outside world in order to win respect. Internally, the church needs unity, mutual love and an absence of rifts. Externally, the church should build excellent relations with government departments and local residents.
Unity is strength, and mutual understanding brings mutual support.
Finally, it needs to be acknowledged that this is a spiritual battleground. Having enough money to build churches is not enough. Believers have to accompany this with the building up of the spiritual life of the church through watchful prayer.
