We can do all things through Christ who strengthens us, but frankly we won't if we're too afraid to try.
A big difference exists between trying to manipulate God to give us what we want and cooperating with God so He can give us what He wants.
Trying to obey and serve God before we've come to love Him can be exhausting.
Anything God does, the enemy tries to counterfeit. We have to be on guard against the enemy!
