People often mistake wishing to God as being the same as praying to God.
A wish is defined as a desire to have something that will probably not happen. Often, people dream of a particular outcome, so they wish upon God and hope it will happen. They don’t expect it to occur, but it would be nice if it did.
Prayer is a request presented to God that will further his work and worship here on earth. A righteous person gives their needs to God and expects him to respond with power and grace. Therefore, prayer is rooted in trust and comes with a level of expectation.
Save your wishes for birthdays and falling stars. Believers are people who pray in faith.
