All Is Grace. Everything Happening in My Life

Galatians 4 is a reference to Genesis 21. The story of Abraham and Sarah dismissing Hagar and Ishmael. It happens on the day that Isaac is weaned. That marries very closely to Hebrews 513. For every spiritual infant who lives on milk is not yet pierced with the revelation of righteousness. If you try to get rid of legalism without knowing righteousness, you can end up in lawlessness.
