Heb 5:13-14 for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.
Babies want and need milk. As they grow they begin to eat solid food. As a spiritual metaphor, this means new believers need to first receive the basic Gospel news, but to grow the believer needs to be trained in the whole of Scripture. As for me, I want meat and potatoes. I want to know enough and be sufficiently filled with the Holy Spirit to distinguish right and wrong and also be strong enough to stand up against evil. It is essential to be strong so as to endure and at the end be standing. If you can’t tell good from evil, you probably won’t be standing when Satan tries to beat you down.
