The charity said the free platform is the first of its kind in the UK. The Resource Hub is geared towards church leaders, small groups and individual Christians.
So far, the website includes a handbook for doing mission on housing estates, interactive Bible studies, prayer exercises and articles from guest contributors on the latest theological and missional developments.
There are also videos, study guides for small groups, as well as video and audio recordings of missionaries telling stories of transformation from around the world.
Helen Brook, church mission adviser at CMS, said the website aims to help people get over fears about mission.
"A recent survey we conducted among 2,000 Christians shows that while nine out of ten Christians believe mission is for all, 44 per cent said they were not putting their mission call into action," she said.
"We have designed this new platform as a tool to encourage Christians wanting to dive into mission."
"The Resource Hub has been designed... to help people overcome their fears or misconceptions about mission and set them free to put their call into action, whether overseas or over the road."
