My beloved do not be concerned with/about what others THINK about/of you; BUT, be concerned and make it your business to KNOW what GOD KNOWS of/about you. Remember: We indeed do not know our own hearts.
Jeremiah 17:9-10 KJV
[9] The heart is deceitful above all things, and desperately wicked: who can know it? [10] I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
Let that marinate.
