"The Lord had called Paul to carry His name before the Gentiles and to suffer much for the sake of His name (Acts 9:15-16). Thus, Paul's great passion was that Christ be 'proclaimed' and that Christ be 'honored' in [his] body, whether by life or death' (Philippians 1:18-20). If you had asked Paul, 'Why are you evangelizing?' he would reply, 'Because I want the name of Jesus to be magnified in all nations.' Is God's name your heartbeat? Does it bother you that the non-Christians around you are not magnifying Christ's name? If not, ask the Lord to give you a fresh glimpse of His unrivaled majesty today.
Let the Gospel's advance be your heartbeat.
Gospel Meditations for Missions--The Evangelist's Heartbeat--Day 19
If you have a copy of "Gospel Meditations for Missions", I would highly recommend reading the devotional for Day 19. It would be silly for me to quote the entire entry for the day on this blog, so I didn't do that (though I was tempted), but one tiny quote doesn't do it justice. There is much to think about and take action on within this one little reading, so I definitely suggest checking it out for yourself.
