It’s true. In church we’ve nodded our heads and said, “Yes, amen. God’s Word is true.” Then we walked outside and came face-to-face with sickness or some other kind of problem and we challenged the truth of the Word of God with our thoughts, our words and our actions. We followed the course of fear instead of simply expecting God to do what He said He would do for us.
Some people would say, “Well, it’s not that I thought God was lying. It’s just that we can never really know what He is going to do.”
Yes, we can! God told us what He is going to do! He’s literally given us His Word on it. Hebrews 6:16-18 in the "New Living Translation" puts it this way:
"Now when people take an oath, they call on someone greater than themselves to hold them to it. And without any question that oath is binding. God also bound himself with an oath, so that those who received the promise could be perfectly sure that he would never change his mind. So God has given both his promise and his oath. These two things are unchangeable because it is impossible for God to lie. Therefore, we who have fled to him for refuge can have great confidence as we hold to the hope that lies before us."
This simply means that men make oaths or contracts in order to settle disputes. Contracts clearly define responsibilities and obligations. As long as everyone is true to their word, there’s no room for questioning what anyone will do.
