"He took the twelve aside..." Luke 18:31
The "bravery" of God trusting His creation. When we think we have no value and nothing to contribute is when God can use us the most. It's when we think we are useful to God is when He can't use us because we feel we have our own purposes to accomplish.
We bring NOTHING to the table of salvation, it's by God's grace ALONE. That's probably why people struggle with the message of salvation. Surely there must be more to it?? Perhaps if I also accomplish these extra items then God will accept me?
Nope. Salvation through Christ ALONE.
As my pastor is fond of quoting Paul, "He must increase, I must decrease!"
