Accordingly, it often happens that Christians, after they have been especially favored with the tokens of
the divine favor, soon relapse into their former state, or fall into some sin that grieves the hearts of their brethren, or wounds the cause of religion. So it is in revivals; so it is in individuals. Churches that are thus favored are filled with joy, and love, and peace. Yet they become self-confident and elated; they lose their humility and their sense of their dependence; they cease to be watchful and prayerful, supposing that all is safe; and the result often is, that a season of revival is succeeded by a time of coldness and declension. And thus, too, it is with individuals. Just the opposite effect is produced from what should be, and from what need be. Christians should then be especially on their guard; and if they then availed themselves of their elevated advantages, churches might be favored with continued revivals and ever-growing piety; and individuals might be filled with joy, and peace, and holiness, and ever-expanding and increasing love. (Excerpt from Albert Barnes' Notes of the Bible)
"Therefore let anyone who thinks he stands [who feels sure that he has a steadfast mind and is standing firm], take heed lest he fall [into sin]." (1 Corinthians 10:12, AMP). Keep yourself from being self-confident and elated. Keep your heart from being bloated. Keep your home house fly free.
Albert Barnes is accurate in his description. Our prayer to God differs according to our current situation, whether we're on the mountain top of happiness or in the valley of sorrow. That's the reason why the tragedies in life are called the God's blessings in disguise. Those who are happy and feel blessed today are in danger of falling from the mountain top. Those who are in the valley of death and sorrow are in great need of God, more than anyone else. Blessed are they that mourn: for they shall be comforted (Psa. 126:5-6; Isa. 61:2-3; Isa. 30:9; Mt. 5:4; 1 Peter 4:13-14).
Only real friends can understand the situation in the valley. Real friends bless their enemies; they have no cursing under their breath. They laugh with their happy friends when they’re happy; they share tears when they’re down. They get along with each other; they don’t get stuck-up. They make friends with nobodies; they don’t become the great somebody; they don't have BLOATED FEELING (Romans 12:14-16, MSG).
