“Yet a little while,
and the coming one will come and will not delay;
38 but my righteous one shall live by faith,
and if he shrinks back,
my soul has no pleasure in him.”
39 But we are not of those who shrink back and are destroyed, but of those who have faith and preserve their souls. 
I trust that this week, the texts have provoked us to love and good deeds as we actively look for the appearing of Christ. In chapter nine, verses 26-28, just previous to this text, the author of Hebrews has explained the fact that Christ has already appeared once to put away sin by the sacrifice of himself and that it is appointed for man to die once and after that comes judgment.
And then you almost miss the significance of what he writes next: …so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him. That means this second appearing, the Parousia will not be a fearful thing for those who are following Christ, but a joyous occasion of our final salvation. Our bodies will be changed, temptations will be no more and so shall we ever be with the Lord.
And so in our text, the thoughts of Habakkuk 2:3–4 are cited to express the certainty of God’s coming intervention for those who trust him. Those who are righteous will live by faith. Their faith will support them as they wait confidently for God to act.
Just as the author of Hebrews desired to encourage his readers to be patient until the coming of the Lord, so the words remain true for us today. We are to live our lives each day by our faith. To contextually bring in another encouragement from the same chapter, keep on encouraging one another with love and good deeds, don’t quit meeting together and all the more as we see The Day drawing near. He who is coming WILL come!
As each of us goes to worship tomorrow, let’s not forget that one of the reasons we do so is to have our faith strengthened and encouraged. Whatever you do, go worship together with other believers.
