It is true, religion in the souls of men is the immediate work of God, and all our natural endeavors can neither produce it alone, nor merit those supernatural aids by which it must be wrought: the Holy Ghost must come upon us, and the power of the Highest must overshadow us, before that holy thing can be begotten, and Christ be formed in us: but yet we must not expect that this whole work should be done without any concurring endeavours of our own: we must not lie loitering in the ditch, and wait till Omnipotence pull us from thence; no, no! we must bestir ourselves to our utmost capacities, and then we may hope that, ‘our labour shall not be in vain in the Lord ‘ (1 Corinthians 15:58).

Henry Scougal, The Life of God in the Soul of Man, 97ff.

And then looking back on the “bestirring of ourselves” we will say that it was all of grace.
