When you are born-again (John 3:3) it is much like the first birth in that you must have someone take care of your [spiritual] needs and must start learning spiritual things; how to eat, how to walk, and how to talk.
Let’s start with what to eat.
I know many new Christians that want to dive into really deep mysteries of the Bible; Revelation comes to mind!
That would be like feeding a baby a spicy pizza with jalapenos.
You are like babies who need milk and cannot eat solid food. For someone who lives on milk is still an infant and doesn’t know how to do what is right. Solid food is for those who are mature, who through training have the skill to recognize the difference between right and wrong. Heb 5:12-14
I know a mom that has been nursing her baby for almost a year. The child does eat some solid food also but is still dependent upon mom. It’s a wonderful relationship for both. There is love, security, trust, and comfort for the child.
Isn’t that what your relationship with Christ should be like?
The milk of the word is to help wean us away from the sinful nature.
I had to feed you with milk, not with solid food, because you weren’t ready for anything stronger. And you still aren’t ready, for you are still controlled by your sinful nature. 1 Cor 3:2-3
The milk of God’s word should teach how to live properly, including how to walk and to talk.
Quickly each Christian can learn we walk by faith, not by sight (2 Cor 5:7) and let no corrupt word proceed out of your mouth. Eph 4:29
The time will come when the born-again person can eat more solid teaching from the Bible. There will be that time to study Revelation. But you must crawl before you walk; and you must walk before you run.
