Bible Verse for Today: Proverbs 3:1-6 1 My son, do not forget my teaching. Keep my commands in your heart. 2 They will help you live for many years. They will bring you success. 3 Don't let love and truth ever leave you. Tie them around your neck. Write them on the tablet of your heart. 4 Then you will find favor and a good name in the eyes of God and people. 5 Trust in the Lord with all your heart. Do not depend on your own understanding. 6 In all your ways remember him. Then he will make your paths smooth and straight.
