1) Meditating on God's word day and night will lead to prosperity and success because God will be with you wherever you go.
2) Suffering for doing good things should not be feared, and Christians should always be ready to gently defend their faith in God to those who question it. Having a clear conscience and doing good in the name of Christ can put to shame those who falsely accuse Christians of wrongdoing. It is better to suffer for doing right than wrong.
