don't lean on your own understand don't let that be the reason you can't get a miracle or sign . I understand your question is why do I need to hear this well as a Christian you have to know that God is always wanted us to look to him for understanding. not leaning on your own understand because God wants us to know that the understand of him is not based on human things. it is based on the lord God revelation of what he wants us to do or what he wants us to know that is why we have to be careful who we are letting influence us into doing things that may not be a good thing. because you're disobedience can lead you astray and if you don't let God bible verses and scriptures be a uplift instead using them to justify why you are the way you are. no the bible was created by God to help us give us a understanding of life in God that we may see the glory of God manifest in your life .let your worship in your heart speak loudly than your burdens and your sorrows of tomorrow and today. praise the lord God for your getting through it .Psalm 98:1-2 tell us that Go ahead—sing your brand-new song to the Lord!
He is famous for his miracles and marvels,
for he is victorious through his mighty power and holy strength.
2 Everyone knows how God has saved us,
for he has displayed his justice throughout history.
