About Operation Serve® International

Operation Serve® International (OSI) is a non-denominational ministry established in 1983 with a passion to extend the Kingdom of God on earth. OSI deploys hundreds of Great Commission minded Christians to serve the poor and needy as well as train national leaders. As a Kingdom minded ministry our teams come from a wide range of Christian denominations and affiliations. Our motto is “Sharing the Love of Christ in Word & Deed!”

Experience the thrill of touching the lives of others for Christ.

The Thrill of OSI

Travel to other countries, help the helpless, and change the world. That is what you can expect from a trip with Operation Serve International. OSI provides physical and spiritual aid to the poor and destitute living in Mexico and Egypt. Christ who made the ultimate sacrifice said:
   “This is my commandment, that you love one another as I have loved you” John 15:12.
   Go on an OSI mission trip and spread Gods love through word and deed.

Focus Up

The work and ministry of OSI demonstrate Christ through word and deed.

Focus Up

Our focus is to bring people to Christ through word and deed.
   “Dear children, Let us not love with words or tongue but with actions and in truth.” 1 John3:18
   By meeting physical needs through medical, optical, dental, and personal hygiene, OSI is able to open the doors to meeting the spiritual needs as well. People just like you who keep their eyes fixed on the Lord accomplish the Focus of OSI.

Change the World

OSI uses four methods to change the world around us: Mercy Missions (Short-Term Teams), Education and Community Development, Indigenous Leadership Training, and Oasis Publishing.
   Are you ready for God to show up? Check out our short term Mercy Missions teams! In one week you can change someone’s eternity.
   Do you want to live in community with the world around you? Through Education and Community Development, we are strengthening the people we serve and preparing them for God’s plan.

“To change a country you must first affect its leaders,” said Dr. Sameh Sadik Executive Director of OSI. With Leadership Training and Oasis Publishing, we are doing just that! By hosting conferences and offering relevant Biblically sound materials in native languages, OSI helps to strengthen existing ministry in their presentation of the Gospel.
