In this parable, Jesus compares entering the kingdom of heaven to attending a wedding. If a guest is dressed inappropriately, or if they misbehave, they will be asked to leave. God sent many prophets and finally his Son, to tell us what we must do to enter his kingdom. Jesus says that while all are invited, only those who do the will of God will be chosen to attend the heavenly banquet.
Lord, help me to clothe myself in good thoughts, words, and actions, so I may enter your kingdom.
