In verse 11 he then speaks about mutually encouraging each other. This still applies today! We need the support and mutual encouragement of our faith family and of other believers. Following or serving Jesus is not something that we can do by ourselves.
In verse 16 Paul writes "For I am not ashamed of the gospel; it is the power of God for salvation to everyone who has faith ..." Do you ever find yourself not sharing your faith for fear that you might be offending someone? Is your faith something you freely share with others?
