Wherefore let him that thinketh he standeth take heed lest he fall.
–1 Corinthians 10:12
It is possible to fall.
Therefore, we must consider what it means to stand.
We stand when our every confidence is in God:
Pride goeth before destruction, and an haughty spirit before a fall. Better it is to be of an humble spirit with the lowly, than to divide the spoil with the proud.
This confidence extends to the fulfillment of every natural need:
I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
If we believe God, we have no need. We find rest and safety in His sheep pen. Every day, He leads us to good pasture and still waters. He protects us from the terrors of night and the dangers of day. He foresees and fulfills every need and blesses us with an overabundance of all things (Psalm 23; John 10:1-4).
Why then do men fall?
They have not prepared to stand:
Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
At all times, our focus is to be upon Christ, as revealed through His word by the power of the Holy Spirit.
… his divine power hath given unto us all things that pertain unto life [our natural needs and duties] and godliness [our spiritual walk] …
