2 Timothy 2:15 “Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.”
This verse is usually read a “Study to show oneself approved to God”. The word “study” in this passage does not mean to pursue knowledge by reading, etc. Rather, it involves much more than just taking in knowledge. It’s used for a workman giving diligence, endeavoring or exerting oneself.
The most common way this verse is interpreted is to say that if we study well, God approves of us and what we have done. It is more correctly interpreted that through our study, we prove to ourselves that we have been approved, or accepted, of God through Jesus Christ.
Studying doesn’t make us more accepted by God, nor does our lack of study make us less accepted by God. By our study, we will be made more aware that God has already accepted us, and our lack of study will make us less aware of that.
