A quote from The Village Church on Baptism

As an explicit and universal command within Scripture, we believe baptism is not merely an issue of wisdom to be applied subjectively, but of humble obedience to God’s declared will for His people. In light of this position, we would hold that one who professes to be a believer and yet has refused and still declines the call to be baptized is engaged in ongoing, unrepentant sin. In order to head off the subsequent need for church discipline created by accepting membership in such a situation, we have established this issue as a potential litmus test of a heart of humility and worshipful obedience to the commands of the God Who is worthy of our deepest praise and submission.
