Matthew 22:12 He asked, “How did you get in here without wedding clothes, friend?” The man was speechless.
Just because the king had told the servants to go out and invite anyone in to the wedding banquet did not automatically give everyone the right to come in…
Does that sound wrong? Well, the servants invited lots of people but they would have been told it was a wedding banquet and they would have to dress accordingly.
This person had not listened and assumed they would be let in anyway… Never assume!
The same is our entry to Heaven. We are all invited, but we do have to believe in Christ first of all.
