In light of Jesus’ resurrection and ascension the question may be asked, “Now what do we do?” The disciples decided to gather, pray and lead. Peter rose up as a leader among the group and decided that next decision was to replace the disciple who betrayed them all, Judas. The driving force behind this decision was the Scriptures themselves (1:16-20). Through his meditations on the Psalms, Peter saw the reigns of David and Jesus as one and took guidance from David’s wisdom.
