If you do--that God wants only the best for you--then why do we struggle everyday?
Do you know His heart? What He feels towards you, what He thinks about you, what He's trying to tell you?
If someone wished you "God be with you", do you wonder, isn't He already with me, or do you think, sure, that's up to God?
Is God passive? Does He wait for us to fulfil certain conditions before moving us along? Or is He actively working in our lives? Then what part do we play?
