After this there was a feast of the Jews, and Jesus went up to Jerusalem. Now there is in Jerusalem by the Sheep Gate a pool, which is called in Hebrew, Bethesda, having five porches. In these lay a great multitude of sick people, blind, lame, paralyzed, waiting for the moving of the water. For an angel went down at a certain time into the pool and stirred up the water; then whoever stepped in first, after the stirring of the water, was made well of whatever disease he had. (John 5:1-4 NKJV)
The blind man is waiting for the water to move. But he can not see the water moving. The first person to get into the water will get healed. Given that the blind man cannot see, by the time he hears that the water is moving, its always too late. This is wishful thinking.
There is no indication that blind people have been healed at the pool of Bethesda. Is the methodology for his healing correct? No.
There is a difference between wishful thinking and faith
The blind man was trusting a system and not a person. When we trust a system and not a Source, we are wishful thinkers not people with faith. God can change the system in which He operates. We serve a moving God.
But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him. (Hebrews 11:6 NKJV)
When you seek a solution, you are systematic. When you seek Him, you are a man/woman of faith.
When you are surrounded by systematic people, you will be a in the valley for a long time. Faith doesn't come from people who are in the same situation. Wishful thinkers operate on man's good advice.
When you do things half-heartedly you are a wishful thinker. When you are caught in the middle of a problem, faith will take you out, wishful thinking will keep you there.
Go the whole nine yards with Jesus, you can’t go halfhearted or half way.
