Grace Koster


Hi! My name is Grace Koster and I am a missionary with YWAM (Youth With A Mission) in Kona, Hawaii!

YWAM is a non-profit missions organization that has as its goal: to see young people know God, and to make him known. I did my DTS (Discipleship Training School) in 2022, where my heart for missions grew. During DTS my heart was completely changed to fully understand God's love for me and for others. God revealed to me His heart for the lost and put me on fire for Him and the nations.

God had called me to Brazil for my DTS outreach and in that time God showed me just how faithful he is. I was able to see so many Brazilians saying yes to The Great Commission and partner with God to see so many lives healed and saved! While in Brazil one of my roles was media for my team. During this time of growing my gift with God, He revealed to me the importance of my gift in missions.

For the next 2 years I have committed to the join media team in Kona where I will be using media to reach our generation!! I will be serving on and off campus and have many opportunities to go to different nations to serve and partner with Gods heart to capture the nations in his eyes to show his love.

Would you prayerfully consider partnering with me in prayer and financially to see a generation saved across the nations?!
