i had a congregant come to me after a service to ask me a question about faith. They said they had been in a study that week and the one leading the study stated that in heaven there is no faith and hope, only love. They asked me what i thought. I addressed the point of faith from the perspective of it being both a noun and a verb in the Greek, pistos and pisteuo. I said that it seems to me that you would always have faith as it is a by product, a possession of your exercise in belief or trust which is the understanding for the Gk. verb for faith.
I hopped on Logos first thing this morning and the only help i could find was in Grudem's Systematic Theology which has as a footnote in Chapter 52 on Gifts of the Holy Spirit, "Some argue that faith and hope will not endure in heaven, so 1 Cor. 13:13 only means that faith and hope last until, not beyond, Christ's return. However, if faith is dependence on God and trust in him, and if hope is a confident expectation of future blessings to be received from God, then there is no reason to think that we will cease to have faith and hope in heaven. (See Carson's good discussion of faith, hope, and love as "eternally permanent virtues" in Showing the Spirit, pp.74-75)
