Charles H. Spurgeon on Psalms 119:174

I have lounged for thy salvation, O LORD. He speaks like old Jacob on his deathbed; indeed, all saints, both in prayer and in death, appear as one, in word, and deed, and mind. He knew God's salvation, and yet he longed for it; that is to say, he had experienced a share of it, and he was therefore led to expect something yet higher and more complete. There is a salvation yet to come, when we shall be clean delivered from the body of this death, set free from all the turmoil and trouble of this mortal life, raised above the temptations and assaults of Satan, and brought near unto our God, to be like him and with him for ever and ever.

I have longed for thy salvation, O Jehovah; and thy law is my delight. The first clause tells us what the saint longs for, and this informs us what is his present satisfaction. God's law, contained in the ten commandments, gives joy to believers. God's law, that is, the entire Bible, is a well spring of consolation and enjoyment to all who receive it. Though we have not yet reached the fulness of our salvation, yet we find in God's word so much concerning a present salvation that we are even now delighted.
