'Examine yourselves...' 2 Corinthians 13:5 NKJV
If you are serious about changing:
(1) The first person you must know is yourself. Human nature seems to endow us with the ability to size up everybody except ourselves. If you're not comfortable with yourself, you won't be comfortable with others. And if you don't believe in yourself, your lack of self-worth will undermine you in life. One marriage counselor says, 'The most important relationship you will ever have is with yourself. You've got to be your own best friend first.' But how can you be best friends with someone you don't know, like, or respect? That's why it's important to discover what God's called you to be, then work at becoming that person. And you won't get there overnight; it's a process one that requires a mindset of honesty, frequent repentance and constant self-correction. But if you commit yourself to it God will help you.
(2) The first person you must work on is yourself. Dr. Samuel Johnson said, 'He who has so little knowledge of human nature as to seek happiness by changing anything but his own disposition, will waste his life in fruitless efforts, and multiply the grief which he purposes to remove.' The Bible says, 'Examine yourselves.' Only as we examine ourselves before God do we discover where our true battles lie. Then we've a choice. We can be like the man who visited his doctor and found out he'd serious health issues. When the doctor showed him his x-rays and suggested surgery, the man asked, 'Ok, but how much would you charge just to touch up the x-rays?' Or, you can decide to change!
