You do not lack self-discipline because you lack willpower. Your willpower has simply conquered your desires for God.
Excerpt:
“Our will always obeys our wants — our real wants, not our fantasy wants. And our real wants are based on our real beliefs, not our fantasy beliefs.
So, when we can’t sustain some new self-discipline regimen, it’s very likely that our resolve was based on a fantasy reward. What typically happens is we imagine what experiencing the benefits of attaining some goal might feel like — perhaps a fit body, or reading the Bible in a year, or some kind of career advancement, or the fruit of more intercessory prayer, or a financial savings goal, or a new boldness in evangelism. What we imagine appears desirable to us. We feel a burst of inspiration, so we make a resolve. We think (or want to think) our inspiration stems from a new conviction that the reward we imagine will make us happy.
But once we experience the unpleasantness of self-denial, the inspiration evaporates and the goal no longer seems worth it, so we give it up. What happened? We liked the imagination of the reward, but the reward itself wasn’t real enough to fuel our discipline — we didn’t really believe in it. It was a fantasy. And when the fantasy was dispelled, we realized we wanted another reward more and our will followed.
It wasn’t a lack of will power; it was a lack of reward power. [. . .]
That is the key to self-discipline: our real belief that the pleasures of a reward will be worth the denial of lesser pleasures. And that’s what nourishes the spiritual fruit of self-control in our lives (Galatians 5:23): wanting the rewards the Spirit offers us more than the rewards sin or the world offer us.
This is really good news to self-discipline stumblers like us! If we’re not pursuing the kingdom of God first (Matthew 6:33), if the surpassing worth of knowing Christ isn’t causing us to count all else as rubbish (Philippians 3:8), the Spirit’s remedy to our problem is not more white-knuckled, duty-motivated efforts to be more disciplined. Rather, the Spirit is inviting us into greater delight. He wants us to explore and examine the imperishable reward God longs to give us with all his heart and soul — to plead that the eyes of our heart will be enlightened to see it (Ephesians 1:17) — knowing that the more we seek to see, the more he’ll reveal and help us believe. And the more that happens, the more we’ll view self-discipline, not as a drudgery to be avoided, but as a means to the joy we really want.”
