Key Ministries
- Mobilisation and Sending
By prayer, SIM USA recruits, prepares and journeys with Christians sent by their churches to make disciples of Jesus Christ where He is least known. This includes mentoring and supporting mission workers throughout their calling, from initial enquiry to long-term service. - Engagement and Learning
SIM USA seeks to inspire and equip the roughly 30 million Americans who read the Bible daily to engage in global missions. Through its website, simusa.org, SIM USA offers a learning centre with resources, stories and opportunities to get involved in God’s global mission, whether through going, giving, praying or mobilising others.
Spiritual Landscape in the US
The spiritual climate in the United States has seen notable shifts in recent decades. While Christianity remains the dominant faith, there has been a steady decline in religious affiliation, with a growing segment of the population identifying as “spiritual but not religious”. Church attendance has dropped, especially among younger generations, many of whom express scepticism toward organised religion.
Despite this trend, there is a simultaneous resurgence of interest in authentic Christian community, particularly among younger believers seeking meaningful connection and purpose. Many evangelical churches across the US are becoming more ethnically diverse and are engaging more intentionally in global mission and the Great Commission.
Please pray
- Pray for the Holy Spirit to use churches, mission partners and SIM USA’s Culture ConneXions team in urban centres, as they seek to bring God’s good news to people who have not heard it
- Pray for increased SIM partnerships and long-term mission workers from among African-American, Asian-American and Hispanic churches
- Pray for the US Church to be mobilised to fulfil the Great Commission, both locally and globally
