I can wear a mask, or I can pretend but I know that without a doubt he knows, God knows the real me. There is absolutely nothing hidden from him. So, there is no reason for me to avoid confessing my sin before him, for he already knows. In that, is my healing, my redemption through Christ.
O LORD, thou hast searched me, and known me. 2 Thou knowest my downsitting and mine uprising; thou understandest my thought afar off. 3. Thou coompassest my path and my lying down, and art acquainted with all my ways. 4. For there is not a word in my tongue, but lo, O LORD, thou knowest it altogether. 5. Thou hast beset me behind and before, and laid thine hand upon me. 6. Such knowledge is too wonderful for me; it is high, I cannot attain unto it. Psalm 139:1-6 KJV
The whole of Psalm 139 is worth reading, for it declares that it is God who formed us, created us, and that we are fearfully and wonderfully made.
Have a great Sunday!
