We are His creation. If we constantly hate what we see every time we look in the mirror, how can we trust that God has a great plan for our lives? The reality is that the picture we see in the mirror is His greatest work. We are His creation.
How He created us, whether we like it or not, was part of His plan and there is an acceptance we have to come to. The message of Jesus has always been one saying we are accepted, made perfect, and loved beyond comprehension. Ground yourself in this reality and self-rejection will begin to lose its power.
