Don't be so certain to think that your faith is unflappable. Even faithful Christians have a very hard time staying faithful. After the Israelites were delivered from Egypt (they asked Him to free them), they became hungry while on the journey to the Promised Land. They then asked God to send them back because they were hungry. No perspective at all!
It's amazing how the body will make you want to go back to what you know even when it is not good for you.
We are learning about how God is the vine and we are the branches that are meant to bear fruit. Part of this fruit-bearing is related to growth and sometimes growth hurts. Don’t get discouraged in the growth process. It will be well worth it! - Meghan
