And now the last thing to be noted this assurance is attained and sustained.
The words of the original convey even more forcibly than those of our translation the thought of David's own action in securing him the hold of God as his. He strengthened himself in the Lord his God.' The Hebrew conveys the notion of effort, persistent and continuous; and it tells us this, that when things are as black as they were round David at that hour--it is not a matter of course, even for a good man, that there shall well up in his heart this tranquilizing and victorious conviction; but he has to set himself to reach and to keep it. God will give it, but He will not give it unless the man strains after it. David' strengthened himself in the Lord,' and if he had not doggedly set about resisting the pressure of circumstances, and flinging himself as it were, by an effort, into the arms of God, circumstances would have been too strong for him, and despair would have shrouded his soul. In the darkest moment it is possible for a man to surround himself with God's light, but even in the brightest it is not possible to do so unless he makes a serious effort.
That effort must consist mainly in two things. One is that we shall honestly try to occupy our minds, as well as our hearts, with the truth which certifies to us that God is, in very deed, ours.' If we never think, or think languidly and rarely, about what God has revealed to us, by the word and life and death and intercession of Jesus Christ, concerning Himself, His heart of love towards us, and His relations to us, then we shall not have, either in the time of disaster or of joy, the blessed sense that He is indeed ours. If a man will not think about Christian truth he will not have the blessedness of Christian possession of God. There is no mystery about the road to the sweetness and holiness and power that may belong to a Christian. The only way to win them is to be occupied, far more than most of us are, with the plain truths of God's revelation in Jesus Christ. If you never think about them they cannot affect you, and they will not make you sure that God is yours.
But we cannot occupy ourselves with these truths unless we have a distinct and resolute purpose running through our lives, of averting our eyes from the things that might make us lose sight of them and of Him. David had his choice. He could either, as a great many of us do, stand there and look, and look, and look, and see nothing but his disasters, or he could look past them; and see beyond them God. Peter had his choice whether he would look at the water, or whether he would look at Jesus Christ. He chose to look at the water; and when he saw the wind boisterous he began to sink '--of course, and when he looked at Christ and cried: Lord, save me!' he was held up--equally of course. Make the effort not to let the sorrowful things, or the difficult things, or the fearful things, or the joyous things, in your life, absorb you, but turn away, and, as the writer of the Epistle to the Hebrews says, in another connection, look off unto Jesus, the Author and Finisher of faith.' David had to put constraint upon himself, to admit any other thoughts into his mind than those that were pressed into it by the facts before his eyes; but he put on the constraint, and so he was encouraged because he encouraged himself.
There is another thing which we have to make an effort to do, if we would have the blessedness of this conviction filling and flooding our hearts. For the possession is reciprocal; we say, My God,' and He says, My people.' Unless we yield ourselves to Him and say, I am Thine,' we shall never be able to say, Thou art mine.' We must recognize His possession of us; we must yield ourselves; we must obey; we must elect Him as our chief good, we must feel that we are not our own, but bought with a price. And then when we look up into the heavens thus submissive, thus obedient, thus owning His authority and His rights, as well as claiming His love and His tenderness, and cry:' My Father,' He will bend down and whisper into our hearts: Thou art My beloved son.' Then we shall be strong, and of a good courage,' however weak and timid, and we shall be rich, though, like David, we have lost all things.
