If you have Jesus as your Savior, you are on a firm foundation, secure and unshakable.

The new Testament is our workbook, by which and in which we learn to workout our salvation.

But the heart, above all else, is where Jesus should reside, and there, the spirit is above the letter of the law, for Jesus already fulfilled it for you.

Paul knew all this, but because the church was in its infancy, milk is all it could digest.
But He did encourage us to go on to the meat of the word: 1Pe 2:2 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
Heb 5:13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe.

Heb 6:1 Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,

Rom 11:33 O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!
