If the gospel is good(God) news only, grace only, and thereby peace only; Whence cometh bad news?

the bad news i see is that many fellow Christians don't go out and preach the gospel to those that are out there hurting : the drug addict, gang member, prostitute, homeless men and women. It is said to put on the armor of god daily (being ready to preach the good news) so how many people have you reached today.. or haven't making disciples of all nations doesn't happen without us taking action.
