Run away from being your shepherd

Jeremiah 17:1-27
Cursed is the one who trusts in man, who depends on flesh for his strength and whose heart turns away from the Lord. He will be like a bush in the wastelands.
Blessed is the man who trusts in the Lord, whose confidence is in him. He will be like a tree planted by the water.
The heart is deceitful above all things and beyond cure. Who can understand it? I the Lord search the heart and examine the mind, to reward a man according to his conduct, according to what his deeds deserve.
The Lord once again asked Jeremiah went to the gates of Jerusalem reminded each one obey Sabbath day, do not do any word and carry a load on Sabbath day. Let Sabbath day holy.
This chapter contains a mixture of different material: a prophecy of judgment; a wisdom psalm; a personal poetic prophecy-cum-lament; and an early prose prophecy which offers hope of escaping judgment.
Why?
The Lord once again gave people of Judah chance to repent if they could obey Sabbath day, the city and nation will be blessed. Obey the Sabbath day means honor the Lord and obey his commands in his life.
The Lord reward a man and punish a man according to his conduct and his deeds. The Lord knows heart of each person, no one can hide from the Lord.
Blessed one and cursed one is quite obvious contrast here. Trust in the Lord, do not trust in the flesh for his strength.
How?
Make my life holy in my daily life, trust in the Lord, do not rely on flesh. O Lord, Heal me, and I will be healed; save me and I will be saved, for you are the one I praise. I run away from being your shepherd in this moment, I remember I have being your shepherd in my life.
