From the Cambridge Declaration

We reaffirm We reaffirm that in salvation we are rescued from God's wrath by his grace alone. It is the supernatural work of the Holy Spirit that brings us to Christ by releasing us from bondage to sin and raising us from spiritual death to spiritual life.

We deny that salvation is in any sense a human work. Human methods, techniques, or strategies by themselves cannot accomplish this transformation. Faith is not produced by our unregenerate human nature.
