The verse “Let no one look down on you because of your youth” isn’t a license to tell people off when they bring up your age or call you immature. Keep reading the verse and you’ll find the proper response: set a righteous example.
Pray: My heavenly Father, please help me live today. Remind me that Your will is more important than anything in my life. Help me not to allow Satan to get me thinking so much about tomorrow that I fail to live today in a way that pleases You. I ask this in Jesus’ name. Amen.
