(Php 2:13) For it is God which worketh in you both to will and to do of his good pleasure.
The good works that He has prepared for us to do, Eph. 2:10, are works that we do because He works in us.
(Joh 6:28) Then said they unto him, What shall we do, that we might work the works of God?
(Joh 6:29) Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
The Lord Jesus Christ was answering some folks that had just seen Him work a miracle and wanted to be able to do those things as well. He had just told them that the works to labor not for meat that perishes but for the meat that endures unto everlasting life. He was speaking of faith in Himself His answer to them in the first passage that I quoted shows that not only that if they wanted to do the works of God it was to believe on Him. Also He was telling them that faith in Him is a work of God done in the believer by God.
