What makes our personalities differ from each other? We can say its genetics, environmental, etc.. What is the basis of our attitude? We should have a close enough relationship with the Lord that we align our hearts to His word. We all battle certain traits in our behavior, rather its tempers, laziness, nervousness, etc..
The Lord does not see us by our appearance but he sees straight into our hearts. “Do not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.”
For in him we live and move and have our being.’As some of your own poets have said, ‘We are his offspring.’ Acts 17:28
