<p>4:9- see on Gal. 1:1.</p><p><i>But now that you have come to know God, or rather to be known by God</i>- This is not Paul as it were correcting himself. &quot;Rather&quot; would be better rendered 'moreso'. God's knowledge of us is what results in our responding by seeking to know Him. Likewise Paul writes in Phil. 3:12 of grabbing hold of the Lord who had grabbed hold of him. It's not that God plays hard to get, and whoever figures out His word correctly will find Him, hidden behind a mass of theology and interpretation which we must get right. God is in search of man. He knows / recognizes us, and we in turn know Him. Understanding this puts paid to all intellectual pride in having 'found' God by our own searching of the scriptures. The initiative was with Him. Paul considers that coming to believe in imputed righteousness, salvation by faith alone rather than by works of the Law, was and is &quot;to know God&quot;. Justification by works and legalism is an attitude that does not know God. For God is His grace and salvation by that grace.</p><p><i>How can you turn back again to the weak and worthless</i>- Literally, 'poverty stricken, poor'. Paul only elsewhere uses the word in Galatians for the Jewish poor (2:10).</p><p><i>Elementary principles of the world</i>- The Greek for &quot;elements&quot; is always used concerning the elements of the Mosaic Law.</p><p><i>Whose slaves you want to be</i>- There is a tendency in human nature to actually desire servitude. We see it most clearly in the tendency to addiction which there is in us all. But that is just a very public, open manifestation of what is latent within us each. The call to radical freedom in Christ is such that when people really see it, they shy away from it. The Galatians are a parade example for all time.</p><p><i>Once more</i>- See on :8.</p>
