I used to have a letterhead for the ministry when I was travelling around the world for almost 28 years and it gave the ministry name and the statement, “God said it, I believe it and that settles it.”
After a while I realized that: “God said it, and that settles it—whether I believe it or not.”
Psalm 119:89 Forever, O Lord, Your word is settled in heaven.
There is no one challenging God's Word in heaven today because it is already settled.
That's why Jesus taught His disciples on prayer in Matthew 6:9-10 9
In this manner, therefore, pray: Our Father in heaven, Hallowed be Your name.
10 Your kingdom come, Your will be done On earth as it is in heaven.
Jesus was pointing out the utter reliability of God and His Word is sure even when our faith is a bit shaky. And because He himself is one hundred percent faithful, He is worthy of our complete trust.
So our prayer life should be that God's Word be settled in our lives, here on the earth, the same way it is already settled in heaven.
