We are so used to, today, to have self-help remedies. Just follow a set of rules. Just obey these things and you can do this or that. You will have enough willpower to overcome to be able to be what you want to be. But though the Lord gives directions in his word as to how we are to walk, how we are to be strong in the Lord is in the context here. But it is his power that we need and want. If we are to have the power of his might, That is not brought by us. It's not imagined. It is his power.
