Self-discipline is important, and that includes taking care of yourself! How are you doing when it comes to sleep, nutrition, exercise? If we want to be our best selves, we have to take care of ourselves the best we can!
God doesn’t care about what you have to offer; He is more interested in your willingness. As long as you are willing to be open to His opportunities, His prompting, and His leading, He can use you to make a positive difference wherever you are!
There will be times of testing, times of proving, when you have to show God you’ll do the right thing when you don’t feel like it. Keep a good attitude when it’s not fair. Deal with the impurities He brings to light.
