Thus says the Lord: "Let not the wise man glory in his might, let not the rich man glory in his riches, but let him who glories glory in this, that he understands and knows me, that I am the Lord who practices steadfast love, justice, and righteousness in the earth; for in these things I delight." - Jeremiah 9:23-24
We need God. As creatures we need our Creator. We need intimacy with God otherwise our souls will shrivel. To have intimacy with God requires we know his heart. In Jeremiah, God reveals his heart. He tells us the things that bring him delight. Whatever delights us says so much about us.
God tells us we don’t need first of all money or power or great wisdom, we need to know his heart and what delights him. So to understand the heart of God and have intimacy with him we learn that is a God of steadfast love.
We learn that he is a God of steadfast love. His love for us cannot be shaken or moved. He accepts us even when we fail. He sees us warts and all and loves us anyway. Some one once said grace is the reality that we are all bastards but God loves us anyway. We need to know God accepts us and will remain steadfast in his love, otherwise we will begin to look for approval in unhealthy ways.
God is a God who practices justice. God is practicing putting the world in right order. God delights in wrongs being righted. He delights when the poor and the disadvantaged are cared for.
God is a God of righteousness. God delights in putting us back in right relationship with him. He delights in changing and transforming us into a person that can stand before him and be reconciled to him.
We need to know these aspects of God’s heart because otherwise we will go completely off track. If we fail to know God is a God of steadfast love, we run from him when we make mistakes. If we fail to know God is a God of justice, we fail to know him through the poor. If we fail to see God as a God who practices righteous then we tend to try and change ourselves instead of relying in his power.
