Sinners in their natural state lie dead, lifeless, and moveless; they can no more believe in Christ, nor repent, than a dead man can speak or walk: but, in virtue of the promise, the Spirit of life from Christ Jesus, at the time appointed, enters into the dead soul, and quickens it; so that it is no more morally dead, but alive, having new spiritual powers put into it, that were lost by Adam's fall.
Thomas BostonNo work nor deed of ours whatsoever, no not faith itself, can be the condition of the covenant of grace properly so called; but only Christ's fulfilling all righteousness.
Thomas BostonSaving faith is the faith of God's elect; the special gift of God to them, wrought in them by his Spirit.
Thomas BostonThe regenerate man's desires are rectified; they are set on God himself, and the things above... Before, he saw no beauty in Christ, for which he was to be desired; but now he is all he desires, he is altogether lovely... regenerating grace sets the affections so firmly on God, that the man is disposed, at God's command, to quit his hold of every thing else, in order to keep his hold of Christ... If the stream of our affections were never thus turned, we are, doubtless, going down the stream into the pit.
