God Establishes Our Steps

The steps of a good man are ordered by the LORD: and he delighteth in his way. 
Though he fall, he shall not be utterly cast down: for the LORD upholdeth him
with his hand. Psa 37:23-24

Treasury of David-Charles Haddon Spurgeon

Psa_37:23
“The steps of a good man are ordered by the Lord.” All his course of life is graciously ordained, and in lovingkindness all is fixed, settled, and maintained. No reckless fate, no fickle chance rules us; our every step is the subject of divine decree. “He delights in his way,” as parents are pleased with the tottering footsteps of their babes. All that concerns a saint is interesting to his heavenly Father. God loves to view the holy strivings of a soul pressing forward to the skies. In the trials and the joys of the faithful, Jesus has fellowship with them, and delights to be their sympathizing companion.

Psa_37:24
“Though he fall.” Disasters and reverses may lay him low; he may, like Job, be stripped of everything; like Joseph, be put in prison; like Jonah, be cast into the deep. “He shall not be utterly cast down.” He shall not be altogether prostrate. He shall be brought on his knees, but not on his face; or, if laid prone for a moment he shall be up again ere long. No saint shall fall finally or fatally. Sorrow may bring us to the earth, and death may bring us to the grave, but lower we cannot sink, and out of the lowest of all we shall arise to the highest of all. “For the Lord upholdeth him with his hand.” Condescendingly, with his own hand, God upholds his saints; he does not leave them to mere delegated agency, he affords personal assistance. Even in our falls the Lord gives a measure of sustaining. Where grace does not keep from going down, it shall save from keeping down. Job had double wealth at last, Joseph reigned over Egypt, Jonah was safely landed. It is not that the saints are strong, or wise, or meritorious, that therefore they rise after every fall, but because God is their helper, and therefore none can prevail against them. 

God's Hand Upholds Us

Though he fall - That is, though he is sometimes disappointed; though he is not always successful; though he may be unfortunate - yet this will not be final ruin. The word here does not refer to his falling into “sin,” but into misfortune, disappointment, reverses, calamities. The image is that of a man who is walking along on a journey, but who stumbles, or fails to the earth - a representation of one who is not always successful, but who finds disappointment spring up in his path.
He shall not be utterly cast down - The word used here - טול ṭûl - means to “throw down at full length, to prostrate;” then, “to cast out, to throw away.” Compare Isa_22:17; Jer_16:13; Jer_22:26; Jon_1:5, Jon_1:15. Here it means that he would not be “utterly” and “finally” prostrated; he would not fall so that he could not rise again. The calamity would be temporary, and there would be ultimate prosperity.
For the Lord upholdeth him with his hand - It is by no power of his own that he is recovered, but it is because, even when he falls, he is held up by an invisible hand. God will not suffer him to sink to utter ruin.  (Albert Barnes)
