Charles Spurgeon Commentary Philippians 2:13

"for it is God who worketh in you both to will and to work, for his good pleasure." — Philippians 2:13 (ASV)

For it is God which worketh in you both to will and to do of his good pleasure. (Philippians 2:13)

You may very well work out what God works in. If He does not work it in, you will never work it out; but while He works within your spirit both to will and to do, you may safely go on to will and to do; for your willing and your doing will produce lowliness of spirit, and unity of heart with your fellow believers.
