“And Jacob was left alone; and there wrestled a man with him until the breaking of the day. And he saw that he prevailed not against him, he touched the hallow of his thigh; and the hallow of Jacob’s thigh was out of joint, as he wrestled with him. And he said, Let me go, for the day breaketh. And he said, I will not let thee go, execpt thou bless me. And he said unto him, What is thy name? And he said, Jacob. And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with man, and hast prevailed. And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there. And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved” (Genesis 32:24-30, emphasize mine).
In this passage, why did God ask Jacob his name? Was it because God didn’t know his name? Did God forget his name? No. God asked Jacob what he name was to get Jacob to own up to who he really was. You see, Jacob’s name meant “usurper and deciever,” which is exactly what Jacob was. (Read Genesis 25:27-34; 27:1-40.) God wanted Jacob to get honest with Him and acknowledge who he really was.
You know, just as with Jacob, God already knows everything about us. (See Psalm 139.) Yet, we still struggle with being honest with Him about our feelings, our thoughts, and sometimes even our sin. Why do we struggle to much to get honest with Him, when He already knows it anyway?
I believe that it’s such a struggle, because it requires humility. It requires humility to own our thoughts and feelings. It takes humility to say, “Yeah, God, this is what I really think, feel, have done, etc.” It’s a humbling experience.
In conclusion, I encourage you to begin getting honest with God about your thoughts, feeling, sins, etc. After all, He alreadys knows them all anyway, so just go ahead and tell Him!
