That may sound good. That can be a huge mistake. Failure to understand a promise in its context can lead to some very bad conclusions. Too many people go around quoting Bible verses as promises to them as individuals when in fact the promises were given to specific biblical characters, a nation, or only to people of a certain time period. Our emotions have a way of taking over the driver's seat of our lives.
Wrong emotions can overrule right thinking.
As a result, if we have been hurt, we blame God for not doing what we think He promised. The death of a loved one can cause us to lose perspective if we allow our feelings to override the truth about God. A failed romance or a marriage on the rocks can trigger doubts. Personal rejection, failure, loss of a job, physical pain, or injustice can stir up feelings against God that become stronger than any force of reason. When it comes to remembering, we can all be like an absent-minded professor who forgets how to get home.
