Love God

Share Jesus
We come from different places, with different accents and languages, but we had the same heart’s desire – that of extending the Kingdom of God to the ends of the earth until every people group has heard the Good News and His Church has been planted among them.

Carol Acosta
Executive Manager, Founder
Catching a glimpse of the greatness and glory of God, Carol has been “wrecked” by the vision of Revelation 7:9 where people from every nation, tribe, people, and language encircle the Throne shouting praise and worship to the Lamb. Her greatest desire is to be a faithful messenger of the message of reconciliation and to be used to get that message to the ends of the earth, and to the people sitting around her table. Her favorite things are quiet early mornings with the Lord, watching movies with hubby, Enrique, talking through life with son, Gabriel (and his friends), cooking, sharing around the dining room table, reading for wisdom and pleasure, praying with people, teaching, connecting and encouraging co-workers across the world, and game nights with family and friends.
