So often we can be our own worst enemies. We set unrealistic expectations for ourselves and are critical of ourselves when we don't live up to them. But self-criticism is a destructive process than can undermine what God wants to accomplish in our lives.
It's time to borrow a page from God's playbook and give yourself some grace. We are all works in progress. We all make mistakes, we all drop the ball, and we all fall short. So what? When you miss the mark, get up, dust yourself off, and get back in the game.
That's not to make light of the fact that there is always room for improvement, and yes, we should make a habit of evaluating our own lives. Everyone needs to make adjustments at times to get back on track to living a more fulfilled and productive life, but there is a big difference between self-evaluation and self-criticism. Self-evaluation is a constructive, beneficial exercise that helps us recognize the areas where we need to improve. On the other hand, self-criticism is a destructive force that can lead to discouragement, discontent, and depression.
If we want a change in our lives, then instead of constantly criticizing ourselves, and tearing ourselves down, we need to build ourselves up by meditating on and speaking aloud God's Word. God is not in Heaven criticizing you; He is at the head of a great crowd of witnesses cheering you on! God's Word has strength, direction, and promises for you - if you will seek them out. Ask the Lord to help you in areas you need to improve. By His Spirit and through His Word, you can accomplish anything.
Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. Ephesians 4:29 (KJV)
