To do any of this requires a few things.
If our motives are not right, our goals will not be right, and perseverance will be non-existent.
John Piper explains how these three things tie together quite well.
When a disciplined life comes this way, it will last. It will be a joy. It will manifest the fruit of the Spirit.
Study the Word. Get to know God.
Set specific goals. Get accountability.
Continue in prayer asking God to give you the grace to meet the goals you've set.
Watch as your life begins to show forth the glorious fruit of the work of God in your life.
"For it is God who works in you, both to will and to work for his good pleasure."
