When you invite someone to your home, the expectation is that you are the host, and your friend is the guest.  These are two different roles, one to give with generosity and one to receive with thanks.
 
Two disciples had walked back from Jerusalem in Jesus' company, although they did not realise it was Jesus (Luke 24:13-16).  On the road, He explained the Scriptures prophesying the life and death of the Messiah, and that He had to rise from the dead (Luke 24:17-27).  What He said helped them to make sense of the events surrounding His crucifixion, and offered the hope that the women’s reports of seeing Him alive might be true.  This man had something special about Him and although they still did not know His identity, they wanted Him to stay the night at their home (Luke 24:28-29).   

However, halfway through the meal, Jesus changed role - from being the guest to being the host.  He took the bread and broke it ... just as He had at the Last Supper.  At that moment they recognised who He was … “this is my body given for you …” (Luke 22:19).  And then, as soon as they knew who they had been with and welcomed into their home ... He simply disappeared.  But the memory of the conversation stayed with them, as did the shared personal reaction to hearing His explanation of the cross and resurrection.  They described it like a 'burning in their heart'.
 
The truth has an extraordinary ability to evoke a strong personal reaction; either positively as we agree with it, negatively as we try to deny it, and when it burns its way into our conscience.  Truth refuses to go away when we try to ignore it (which is one of the ways we know it is true!).  When people want to hear what the Bible has to say about Jesus and themselves, ignoring it is not a long-term option.  In the same way that the household in Emmaus was only satisfied when they realised that Jesus was speaking to them, those who are concerned about truth will only be fulfilled when they welcome the Saviour.  When that happens, they find that He is not a passive guest, or helper or even an advisor.  When Jesus comes into a person's life, He will take command as the wisdom, righteousness, sanctification and redemption that every human heart needs (1 Corinthians 1:30).  Those who fear Him being in command will not welcome Him, but those who long to be right with God will not be able to escape His grace.  So, let Him take His rightful place in your life; and encourage your friends to welcome Him also.
