All Christians need to concentrate first on spiritual milk before they can take solid food. In these three books of the Bible you will find spiritual milk. Epistle to Hebrews, First epistle of Peter and first epistle to the Corinthians. Hebrews 5:12-14 ESV For though by this time you ought to be teachers, 👉you need someone to teach you again the basic principles of the oracles of God👈. 👉You need milk, not solid food👈, [13] for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. [14] 👉But solid food is for the mature👈, for those who have their powers of discernment trained by constant practice to distinguish good from evil. 1 Peter 2:2 ESV 👉Like newborn infants👈, 👉long for the pure spiritual milk👈, 👉that by it you may grow up into salvation-👈 1 Corinthians 3:2 ESV 👉I fed you with milk👈, 👉not solid food, 👈👉for you were not ready for it.👈 👉And even now you are not yet ready,👈
