Matthew 21:22 (NKJV)
A "Wishing Well" is something that was probably seen more in the past than it is today. A Wishing Well was some type of a well and the idea was if there was something you desired, some wish you had that you wanted to come true, you could go to the Wishing Well and toss in a coin while you made your wish. Supposedly by doing this it became more likely that you would be able to have your wish fulfilled. Most, if not all, people knew this was not a way to actually bring a wish into reality, but it was a nice way for people to dream and wish for something in their life.
For some Christians, prayer and faith are like the experience of a Wishing Well. There is something they need or desire in their life and all they have is a wish that someday, somehow, that wish might come true. Because some believers do not know what God has said in His Word, they have no basis for faith and they really do not believe that what they are asking for will actually come to pass. It can be a very sad thing to see someone in their time of need only wishing for a solution to their problem and the answer that they need. But this is not faith or how a Christian should behave.
We need to learn through the Word of God all about what Jesus did for us and what God has provided for us through Jesus and then put our trust and confidence, our faith, in that. When we face a challenge in our life, when we have a need that must be met, when we have questions about what to do in our life, God has an answer and will help us as we ask in faith. As we take a stand in faith on God's Word, we can know that we will have the answer that we need. We can do more than just wish for our needs to be met, by faith we can believe and receive the things that we need.
