We have a foretaste of heaven inside us

Paul uses the Greek term arrhabôn, a term used in business documents for a downpayment, to describe the gift of the Spirit as a foretaste of our future inheritance (2 Cor 1:22; 5:5; Eph 1:13-14). The Spirit is also the aparchê, the first fruits of our future experience with God (Rom 8:23). Through the Spirit, we await full vindication (Gal 5:5) and experience a foretaste of the coming world (1 Cor 2:9-10).

Heritage and mission, Word and Spirit

Luke’s Gospel begins and ends in Jerusalem. His sequel, the Book of Acts, begins in Jerusalem but ends in Rome. Theologically, this is movement from heritage to mission: holding on to the heritage but moving forward into mission. In the same way, we need to be grounded in the Scriptures, so our action will be consistent with all that God has done before us, yet also moved by the Spirit, so we can reach those parts of humanity not yet reached.
