I’ve been there too. For me, the key to breaking through was trying something new…in my case, Christian meditation in the form of Lectio Divina.
For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. (Hebrews 5:12-14, ESV)
According Hebrews 5:12, the foundational knowledge of salvation and the Gospel should be intimately familiar. The basics have to always be there (to continue the food analogy, we still need dairy in our diet) , however as we progress in the faith it is essential to grow in your understanding of doctrine and God’s character beyond “repentance from dead works…” (Heb. 6:1).
Taking on an unfamiliar spiritual discipline is one way we can progress in our understanding of God’s character and doctrine.
A new-to-you discipline can open doors to experiences and knowledge simply because of its unfamiliarity; it can force you to see things from a different perspective.
When you are compelled to consider spiritual concepts and situations in a new light, you have no choice but to practice your powers of discernment–bringing you to greater maturity in Christ.
