Are you only a Christian in the presence of  God? In his house?   We should strive daily no matter the task or job to flourish in our Christianity.  Others should know of by our thoughts, actions and words.  You can fake others but God knows our hearts and minds.  I know sometimes a person may get tired of praying and forget about God, but we must strive to focus on Him daily to fight our inner battles.  God is Good and merciful, use His mercy.  Trust in Him in time of trouble and He will deliver you.  Always show your true colors, be proud to be a Christian. God Bless.
