Wishy-washy people aren't just unreliable -- they're untrustworthy, because you can never count on them to follow through. And when we as Christians are unreliable in our words and our actions, it reflects on the God we serve. The Lord wants us to be reliable to Him and to other people because we are the conduits He's chosen to carry out His work. When we face obstacles in doing the job He's called us to do, we've got to commit to fighting through it, no matter how hard it gets.
