"The purpose of SIM is to glorify God by planting, strengthening, and partnering with churches around
the world as we:
evangelise the unreached,
minister to human need,
disciple believers into churches,
equip churches to fulfil Christ's Commission."

Our Purpose Statement explained:

The purpose of SIM:
SIM has many functions, responsibilities, and ministries, but only one basic purpose. Everything we do is related to that purpose.

is to glorify God:
This is our highest motivation and all-encompassing purpose. We do not glorify man, organisation, or government, but God, and we evaluate what we do by this standard.

evangelise:
We believe that mankind is lost and needs to be redeemed through Christ Jesus, whom we proclaim as Savior. This distinguishes us from humanitarian agencies.

the unreached:
Our major concern is for unevangelised people groups. We are also concerned for individuals and communities who need a cross-cultural witness if they are to understand the gospel.

minister to human need:
We see ministering to human need as scripturally valid. We do this in the context of our central purpose.

disciple believers:
This involves teaching the Word of God, developing the gifts of the body, bringing believers to maturity in Christ.

into churches:
SIM is a church-planting mission, which distinguishes us from specialised service agencies focused on aviation, linguistics, and medicine. We believe the local church is God's provision for worship, witness, and edification of the believer.

equip churches to fulfil Christ's Commission:
This involves providing skills and leadership training which will enable the churches to be bases for missions. The end result we seek is the local church reaching out to others who are unevangelised.
