One of my favourite parables in the New Testament is the tale of the prodigal son (Luke 15:11-32). God has given His promise that he will never forsake us. Though we may wander, he is ready always, standing at an open door, to welcome us Home with loving arms. He cannot abandon us, because we are and forever will be a part of Him.
But we also have His promise in another sense of the word. When we say that a musician or sportsperson has promise, we mean that they have great potential. This is true of all of us. We hold the promise not to be great in a worldly sense, but to be God-like. To realise our Self as He created us and to be His loving presence.
God's promise is not idle, but a guarantee - surer that anything in this world. If we have God's promise, there can be no insurmountable barrier to realising it. It isn't a question of 'if', but only 'when'.
A happy outcome to all things is sure.
