Disappointment happens when you hoped for an outcome that did not come to pass. Or this outcome failed to meet expectations. In essence, these disappointments are “failed hopes”. We hoped things would turn out a certain way and they didn’t. If it didn’t bring the amount of pleasure you thought it would or things just didn’t turn out the way you wanted then you will be disappointed.
To have faith in Christ is more than reciting a prayer. True faith in Christ produces good works. Where there is no true faith, there is a rebellion against God’s Word. The person who really goes through The Narrow Gate (Christ) also walks in The Narrow Way (follows Christ’s commands). Those that claim faith in Christ without following Christ will find, in the end, that they are not really one of Christ’s people.
