I believe strongly in fighting against social injustices, as long as the Gospel of Christ isn't replaced by a "Social Justice Gospel."
In case you're interested, here are some organizations that I support because of their work with those who are hurting, oppressed, enslaved, hungry, and in need of LOVE:
