Our lives are not in our own hands but in His

I know, LORD, that our lives are not our own. We are not able to plan our own course.
( ...that people's lives are not their own; it is not for them to direct their steps.
...that a person's life is not his to control, nor does a person establish his way in life.)
Jeremiah 10:23 NLT NIV ISV


I have observed something else under the sun. The fastest runner doesn't always win the race, and the strongest warrior doesn't always win the battle. The wise sometimes go hungry, and the skillful are not necessarily wealthy. And those who are educated don't always lead successful lives. It is all decided by chance, by being in the right place at the right time. Eccs 9:11


Proverbs 4:23
Keep your heart with all diligence; for out of it are the issues of life.

In its elements and outward scenery nature is the same to all. Light and night, sun and stars, air and earth and landscapes, offer a common enclosure and background to our existence. But the various impulses and aptitudes for work with which we are born — which press from the very core of our being — diversify the world as widely as if we were distributed upon different globes. To one set of men it is a place to think and learn and grow wise in. Another finds the world a place to work in. Others find it a garden of beauty in which the stars are more valuable as blossoms of poetic light than for their astronomic truth, and the air richer for its hues than for its uses, and the mountains grander for their millinery of mist and shadow and their draperies of verdure and snow than for their service to the climates and housekeeping of nations. Still others see the world as a place to trade in and grow rich — a gorge between gold mountains, where they must quarry. Or it is a pleasure-ground for giddy or elegant enjoyment. It is plain, therefore, that our natural bent in the line of work does a great deal to impress a character upon the universe. Even when no moral quality is involved, we see how life gets coined at our mint, so that the world, God's world, somehow wears the stamp of the die cut into our heart. And temperament, natural temperament, has an effect on life that must be considered in this connection. If a man has a music-box in his heart, the pulse of the sun will seem to beat with it, and the trees to throb and bud with its melody. If his bosom is strung as an AEolian harp, nature will be full of weird and sad cadences. You know how experience, also, interprets the same principle, even in cases where moral considerations are not prominent. You know how a piece of good-fortune brightens the air, how prosperous hours make the globe buoyant, how some impending evil puts the edge of a spiritual eclipse upon the sun as solemnly as the shadow of the moon settles on its burning disc, how suddenly ill-fortune in business will seem to make the very springs of beauty bankrupt, how the sickness of a dear friend turns nature pallid, how the death of wife, husband, or child will convert all the trees to cypress, and set the music of nature in a minor key, as s dirge or requiem. All these facts, which belong rather to the margin of our subject, enforce the duty of "keeping the heart." For though aptitudes, temperaments, and moods have much to do with the tone and quality of our life, states have more. A dark moral state stretches a permanent veil of cloud over the heart, that thins and chills all the light, while a mood or a sorrow may sail only like the swift blackness of a shower through our air. And we can do a great deal to control the moral states of the heart; we are responsible for them. Moral evils, such as envy, avarice, selfishness, license, only vivify with various colouring the one fundamental evil, sin — distance from sympathy with God, alienation from the heavenly Father, indifference or disloyalty to His will and love. This is our central foe. This is what corrupts the issues of life. This is the serpent at the fountain. Back of all sins is sin. The one comprehensive purpose of life is to bring Infinite grace to bear on that, and drive it from the inmost artery of the soul. The first thing to do, in order that such life may issue from your heart, is to get your heart broken. Not because it is totally corrupt, but because it is not centrally dedicated — because God is not invited and admitted to the inner shrine, to rule thence with His wisdom and purity, so that you shall consciously live for Him. This world, with its hard conditions and mysteries, is built for an upper and nether millstone to grind pride out of human hearts, to crush their natural state, so that, in penitence and humility, God may come into the spirit, and the world seem remade because the soul is regenerate in consecration and the beginning of a filial life. You are to keep your heart with all diligence, by desiring and praying for this spirit of sympathy with God and allegiance to Him. And you are also to "keep" it by living in fellowship with great truths and sentiments. If you have had any seasons or season when you have seen the value and blessedness of a religious conception of the universe and of religious principle, honour that; honour your soul's own witness to sacred realities, by trying to keep in the society of those noble truths and ideas.
