Matthew 23:13 But woe to you, scribes and Pharisees, hypocrites! For you shut up the kingdom of heaven against men; for you neither go in yourselves, nor do you allow those who are entering to go in.
If we are going to tell someone it is safe to go out on a branch or to walk across a bridge, then we should be willing to demonstrate it is safe.
If we tell people about God and how great He is, then we should be willing to demonstrate to them we know God and we know His greatness!
Telling people one thing and doing another is one sure way of losing their trust! We need to back up our words with actions.
And this applies to everything we say about God. We need to do things just as we talk about them so others can know the truth and see it in action!
