Study to shew thyself approved to God, A workman that needeth not to be ashamed, rightly dividing the word of truth (2 Timothy 2:15 KJV).
And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge (2 Peter 1:5).
There is a command here to study, and the purpose is not only to satisfy ourselves but to show ourselves approved to God. How is this accomplished? This is done by learning about God and what he expects of us. As we study more it gives us a deeper appreciation of who He is and how powerful He is. Attending Bible study helps us to grow, and as Paul says, not to be ignorant of his word.
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fullness of the Gentiles be come in (Romans 11:25 KJV).
There is a need to get together and study His word. When we study we grow in Knowledge of His word. That is what keeps us from falling short of His expectations (sin).
As newborn babes, desire the sincere milk of the word, that ye may grow thereby (1 Peter 2:2 KJV).
But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To Him be glory both now and forever. Amen (2 Peter 3:18 KJV).
