1 Samuel 16:7, "But the Lord said to Samuel, “Do not consider his appearance or his height, for I have rejected him. The Lord does not look at the things people look at. People look at the outward appearance, but the Lord looks at the heart.”
I just love this verse and I find great comfort in it, especially when the world assumes so much and yet knows so little. God sees our authentic self, which is our heart and mind, without any pretenses. He knows our naked, rock bottom, true soul and will judge us accordingly. So many times, we act like the Pharisees by trying to speak, dress or act to impress others, but God knows the 'fake it till ya make it' performance and is never fooled by it. Isaiah 11:3-4, "He will not judge by what he sees with his eyes, or decide by what he hears with his ears; but with righteousness he will judge the needy, with justice he will give decisions for the poor of the earth."
"The good disposition of the heart, the holiness or goodness of that, recommends us to God, not the majesty of the look, or the strength and stature of the body." Whew, can we all be thankful for that? We are not defined by our bodies but by the condition of our hearts toward God. People will see your life as a reflection of your heart, whatever that may be, with time.
Our problem is that we are quick to judge based on external factors. What if we were judged everyday by how we looked before we 'got ready' for the day? What if we had no control over our hair, smell, breath, etc.? Well, people are judged all the time over things out of their control and it's wrong to assume. Take a minute to think about that... what are you judging others on? Thankfully, God isn't as narrow-minded as we are. He sees what's important in each of us... our heart as for or against Him.
As for myself, I've been humbled many times by people's assumptions because of my small frame. I've learned it's better to give grace than try to defend yourself. Your response is a witness in itself. I'm passed the stage of trying to impress others, but my goal is to keep my heart right and pleasing with God. I am trying to be my authentic self.
