1 Cor 3:2 "I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able." What is the meat and where can I get it? I still feel like all I am fed is milk.
The apostle Paul used the imagery of milk and solid food to describe how he ministered to spiritually immature Christians in Corinth. That imagery is what the writer to the Hebrews also employed (Hebrews 5:13-14).
The “meat” of the Christian faith refers to the deeper doctrines of the Bible and the scriptural truths that are challenging to our human minds.
I would say that a good place to get that “meat” is at congregational Bible studies. Bible classes offer a question and answer and discussion format that can help guide Christians through a study of Scripture—including those parts that are easy and those that are more difficult to understand.
