The Israelites of Moses’ day illustrate a problem facing many who fill our churches today. They know a great deal about Christ, but they do not know him personally-they don’t combine their knowledge with faith. Let the Good News about Christ benefit your life. Believe in him and then act on what you know. Trust in Christ and do what he says.
For indeed we have had the glad tidings [Gospel of God] proclaimed to us just as truly as they [the Israelites of old did when the good news of deliverance from bondage came to them]; but the message they heard did not benefit them, because it was not mixed with faith (with the leaning of the entire personality on God in absolute trust and confidence in His power, wisdom, and goodness) by those who heard it; neither were they united in faith with the ones [Joshua and Caleb] who heard (did believe).
