Are you proud of heart; and have you forgotten God? There are consequence of forgetting God.

For you have forgotten the God of your salvation and have not remembered the Rock that is your strength. Therefore, even though you plant delightful plants, sowing them with imported vine-seedlings, the land will be a desolation. In the day that you plant it, you carefully fence it in, they may sprout on the day you set them out; yes, they may blossom on the very morning you plant them, but you will never pick any grapes from them. Your only harvest will be a load of grief and unrelieved pain. Isaiah 17:10-11
