We are 100 percent responsible for the pursuit of holiness, but at the same time we are 100 percent dependent upon the Holy Spirit to enable us in that pursuit. The pursuit of holiness is not a pull-yourself-up-by-your-own-bootstraps approach to the Christian life.
We take what we think are the tools of spiritual transformation into our own hands and try to sculpt ourselves into robust Christlike specimens. But spiritual transformation is primarily the work of the Holy Spirit. He is the Master Sculptor.
Sanctification is the work of the Holy Spirit in us whereby our inner being is progressively changed, freeing us more and more from sinful traits and developing within us over time the virtues of Christlike character.
Some days we may be more acutely conscious of our sinfulness and hence more aware of our need of His grace, but there is never a day when we can stand before Him on our own two feet of performance, when we are worthy enough to deserve His blessing.
