Jesus is the great Amen. Imagine that all of our prayers are yes and amen in Christ.
Jesus said "If you abide in me and my words abide in you, you will know the truth and the truth will set you free." So... It's the truth we know that saves us. Not merely the truth itself.
Jesus said storms come but the one who weathers the storm and survives is the one whose life is built on the rock of his word. So it's not hearing the word alone, but doing it...and living on it.
Be ye not mere hearers of the word ...but doers as well... And we will see the AMEN to our prayers.
Amen means SO BE IT! and we should trust that.
