I have actually used/read the following resources and found them helpful or enjoyable for me personally.
I came across this series of 5 short videos through Revive Our Hearts. A friend and I committed to watching one each week for 5 weeks. After watching each week, we emailed each other our notes and thoughts on what we learned. I cannot recommend this series highly enough. Whether you’re a new believer in Christ, or a well-seasoned follower of Him, this is a message we all need to be reminded of. Carrie does this in a delightfully gentle, yet engaging and powerful way!
From their own summary of the series:
DEEP IN YOUR HEART, DO YOU EVER FIND YOURSELF ASKING QUESTIONS LIKE THIS: AM I GOOD ENOUGH? DO I HAVE WHAT IT TAKES? WHAT DO PEOPLE THINK OF ME? … FIND FREEDOM FROM THE CRAVING FOR APPROVAL OF OTHERS.
