Here Paul offers an overview of Biblical end times. He lists three events: the Rapture, the Great Tribulation, and Jesus' return. In response, all people are called to a state of readiness, understanding that time is limited. For those who have never come to God, it is a call to start a relationship with God through Jesus--the only provision for their sins before God. For those who have a relationship with God, it is a call to tell others about God's offer of forgiveness, stand against injustice, and ease the sufferings of others, as we await Jesus' return.
