It is common for persons to have various interests in various things. When persons have such interests, they typically learn about what they’re interested in. This may mean reading a book on the subject, watching a documentary, or just getting involved in the activity or topic that interests them. It is often the case that those things that interest people have specific words or terminology associated with the topic. Hockey lovers know what a “hat trick” is; foodies know what a “soufflé” is; gardeners know what a “perennial” is.
Christians profess to worship and adore God Almighty. He, therefore, should be the supreme interest of all those who profess to believe the gospel. So, it is necessary for Christians to learn the terminology associated with our so-great-salvation. This does not mean, however, that every Christian should go to a bible college or seminary, but they should certainly read books that stretch and inform their understanding concerning who God is and what He does. This does not necessitate any advanced, intellectual equipment, for the “law of the LORD” makes “wise the simple” (Ps 19:7).
As well, Christians should join churches where the preaching of the Bible and sound theology is central in the life of the church. In 2 Timothy 4:2, Paul gives his last, corporate command to the church via Timothy, “Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching.” Paul does not tell Timothy to entertain the people of God or to motivate the people of God; he tells him to preach truth to the people of God. If this is the responsibility of the ministers of the gospel, then it follows that the responsibility of the people of God is to attend churches where such is being done, and to give their ears and hearts to the reception of the word of God.
The Psalmist said, “The works of the LORD are great, studied by all who have pleasure in them” (Ps 111:2). Do you agree that God’s works of creation, providence, and redemption are great? Do these works thrill your soul? If you answer “yes” (and you should!), then study them.
