When kids pretend they talk and behave like something is real when it isn’t. Kids aren’t the only ones who pretend, but they are usually more willing to admit it. Adults are often just as active in imagining, and their imagination engines have more horsepower, but they also tend to pretend (a.k.a., lie) that they aren’t pretending, which gets more complicated.
Living by faith is not the same as living by pretend, by fantasy. The similarity between the two is that the subject can’t physically see the object. Faith is “the conviction of things not seen” (Hebrews 11:1), but fantasy is “an idea with no basis in reality” (New Oxford American Dictionary). In both cases there is concentration on something invisible, but faith is the non-fiction form.
In 1 Corinthians 15:12-19 Paul allows an imaginative effort for sake of wondering what it would be like if Christ has not been raised. If that is true, then preaching is pretend, and faith is pretend, and forgiveness is pretend, and the hope of eternal life is pretend. And if all we have is pretend, then we are in realty the most pitiable people on the planet.
But in order for the conclusion of his argument to be true, his premises need to be true. In other words, it’s logical that our faith is pretend only if Christ being raised from the dead is pretend. But what Paul “pretends” is that Christ isn’t raised. What Paul preaches is that Christ has been raised, and so your faith and hope and life are not empty.
Take up real bread and drink real wine; our communion with God and one another in Christ is not pretend.
