Assisting in Mexico

”To bestow on them a crown of beauty instead of ashes.“
–Isaiah 61:3

OSI Field Assistant:

OSI Interns 07Leave a part of your heart in Mexico? Do you long to return? If you have completed our Internship Program, consider serving with us for an entire summer to experience OSI's Missions on a deeper, more challenging level.

“However, I consider my life worth nothing to me, if only I may finish the race and complete the task the Lord Jesus has given me – the task of testifying to the gospel of God’s grace.”
–The Apostle Paul (Acts 20:24)

If your work is not yet finished in Mexico, then OSI pleads you to not forget the task that God has called you to pursue. Come and serve with us again – to be trained further and pushed harder, to be led and to lead others.

Operation Serve International is committed to teaching, leading and raising up the next generation of passionate followers of Christ. Our hearts yearn to see young people excited and zealous for the Lord on the mission field and at home, but we know that this takes much effort and commitment.

We pray that after serving for a summer with OSI, the spark that was once ignited will become a flame, burning with a renewed passion for Jesus and the lost. It is our desire that each Field Assistant will catch the vision of missions with OSI and will be confirmed in the call that God has made on their lives – maybe even serving with us!
