Walking on Air

Hebrews 10 closes with an exhortation to step out in faith and not to shrink back. It's like we're being asked to step off the plane and to walk on the clouds. When you're looking out the plane window at those big chunks of cotton wool floating in the sky, you can easily be forgiven for wanting to jump off the plane and land on them. In some ways faith is like that. You can conceptualise what it might be like to walk the life that's promised, but there's something in you that wants more concrete evidence. Unlike clouds which we know are not walkable, here the Bible is talking about a walk on something which does really hold you up. Your mind asks: can it be done? But here God is urging us to go for it.
