2 Timothy 4:5 But you be watchful in all things, endure afflictions, do the work of an evangelist, fulfil your ministry.
Work for a Christian can mean many things; but all of those things should be focused on Christ.
Sometimes we have to ensure stuff which we think we should not have to, not because we are getting punished for stuff but simply because the world and the people around us may not care for us like we care for them.
God is just and will enable us to do His work if we are willing to listen to His guidance. It is His will that we should obey Him and worship Him with our lives.
Trust Him!
