You can change. None of us is the same person we were a year ago or a decade ago. Our bodies are changing--there's no denying that. But our minds, hearts, habits, personalities, and relationships are changing too. We just need to make sure we are changing for the better, that we're being transformed from glory to glory, that we're growing in the grace and knowledge of Christ. Those who refuse to change are not God-fearers, because those who love Him are changing every day. Don't be afraid to make some changes in your life, and don't be afraid to let Christ change you from within.
I'll go anywhere as long as it's forward. -David Livingstone
Because they have no changes, therefore they fear not God. Psalm 55:19b KJV
