"And Elkanah her husband said unto her, Do what seemeth thee good; tarry until thou have weaned him; only the LORD establish his word. So the woman abode, and gave her son suck until she weaned him." (1 Samuel 1: 23)
As we grow spiritually, we need to know and hear more of God's word:
"As newborn babes, desire the sincere milk of the word, that ye may grow thereby:" (1 Peter 2: 2)
How interesting: the sincere, pure milk of the Word.
How do we understand pure milk?
No mixture, no law and grace: it's all of grace, all of Christ, none of us:
"Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth." (3 John 2)
Prosperity is all about the truth of the Gospel, that every sin is paid for forever, that we do not contribute anything for our righteousness, which is actually His righteousness:
"For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." (2 Corinthians 5: 21)
Yet if we do not rest in His righteousness, then we are still like children:
"13For every one that useth milk is unskilful in the word of righteousness: for he is a babe. 14But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil." (Hebrews 5: 13-14)
Keep reading the Word of God, keeping recceiving revelation of God's righteousness, for all scripture witnesses to our righteousness in Christ (2 Timothy 3: 16).
