Proverbs 29:18... Where there is no vision, the people perish, BUT happy is he who keeps the law.
Yes, we are under grace now. It is by grace that we are saved through faith not by our works lest any man should boast about the things he does, BUT happy is he who keeps the law.
The law is the heart of God, it is what God thinks and how He feels about things.
If we are striving to become more like Jesus, and wanting to please the heart of God, than we should be concerned with God's heart and His feelings on issues in our lives.
Guard your heart with ALL diligence, for out of it are the issues of life. Proverbs 4:3
Because of sin, God has made a way for us to be with Him even though we have broken His law, and broken His heart and that is through the shed blood of His beloved Son Jesus!
"How bare does a place look without Bibles and ministers! and what an easy prey is it to the enemy of souls! That gospel is an open vision, which holds forth Christ, which humbles the sinner and exalts the Saviour, which promotes holiness in the life and conversation: and these are precious truths to keep the soul alive, and prevent it from perishing."~ Matthew Henry
Happy is he who keeps the law, our Father knows best!
