Start with milk and graduate to solids.
If you start with milk and continue on milk you will rapidly find yourself going onto solids like a baby. The milk is the Grace of God.
Understanding the Grace is Wisdom.
Just keep drinking it in, the pure and the simple truths.
The deeper truths come in adulthood.
Functioning through the foundation of Grace means your soul is maturing well.
Heb 5:12-14 Spiritual Immaturity
12 For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. 13 For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. 14 But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil. (NKJV)
2 Like newborn babies you should crave (thirst for, earnestly desire) the pure (unadulterated) spiritual milk, that by it you may be nurtured and grow unto [completed] salvation, 3 Since you have [already] tasted the goodness and kindness of the Lord. (Amplified Bible – AMP)
