That is an excellent analogy. The problem is if one think they're prideful then they've recognized they have sinned. There is no way to notice pride before it happens. It's only after it has occurred that we've notice that we're prideful. One can only keep repeating to ourselves that there is nothing that we have (our jobs, our families, our homes, etc.) that has not been given to us by God.
I think you are so right, brother.
I love this sermon. It is SO insightful. It covers exactly the right issues.
"My son, hear the word of wisdom; if thou art wrong, seek not to correct thine outward life, but seek first to get thy heart correct, for out of it are the issues of life, and thy life shall be pure when once thy heart is so." So if we would get rid of pride, we should not proceed to arrange our dress by adopting some special costume, or to qualify our language, by using an outlandish tongue, but let us seek of God that he would purify our hearts from pride, and then assuredly if pride is purged from the heart, our life also shall be humble. Make the tree good, and then the fruit shall be good; make the fountain pure, and the stream shall be sweet. Oh! that God might grant us all, by his grace, that our hearts may be kept with diligence, so that pride may never enter there lest we be haughty in our hearts, and find that afterwards cometh wrath.
