Has God promised that the motion that brings about the seasons shall not stop?

Genesis 8:22 says that as long as the Earth exists, then the seasons will not cease. But we also know that Creation itself has a finite lifespan, and will cease.

Some things are truly forever, such as God's righteousness and love.

Some are only around for as long as Creation exists: seasons, a chance to see someone come to Faith in Christ, pain and suffering for the believers.
