The longer you are in Christ and the more you take advantage of the means of grace the more you will grow in the knowledge and grace of the Lord Jesus Christ.
This also means that if you attend a church where the Word of God is preached without compromise and if your pastors are teaching "the whole counsel of God" that you will likely hear many messages where you already know the major points of the passage/sermon/study. From God's amazing grace, to man's radical depravity, to the perfect atonement of the Savior's cross.
The following quote reminds us that this is part of the biblically ordained process. "We need to learn and re-learn the same truths again and again, taking them in through a variety of means until they become the very fabric of our thinking and the lens through which we view the world." This is what it means to have "the mind of Christ" and to develop a robustly biblical Christian worldview.
In 2 Peter 1:13 the apostle Peter writes, I think it is right to refresh your memory as long as I live in the tent of this body... Or as one translation puts it, I consider it right, as long as I am in this earthly dwelling, to stir you up by way of reminder.
Pride says, "I already know this. I don't need to go to adult bible study or come to Church this morning to listen to the following exposition of Scripture." Humility says, "We need to learn and re-learn the same truths again and again, taking them in through the variety of means until they become the very fabric of our thinking and the lens through which we view the world." May God grant us grace to apply this wisdom principle to our lives.
