Arthur W. Pink said this quote

Were God to show grace to all of Adam's descendants, men would at once conclude that He was righteously compelled to take them to heaven as meet compensation for allowing the human race to fall into sin. But the great God in under no obligation to any of his creatures, least of all to those who are rebels against him.

...Our Lord Jesus Christ added nothing to God in his essential being and glory, either by what He did or suffered. True, blessedly and gloriously true. He manifested the glory of God to us, but he added nought to God... Christ's goodness and rightousness reached unto His saints in the earth but God was high above and beyond it all....

Here is a fundamental difference between the man of faith and the man of unbelief. The unbeliever is 'of the world', judges everything by worldly standards, views life from the standpoint of time and sense, and weighs everything in the balances of his own carnal making. But the man of faith brings in God, looks at everything from His standpoint, estimates values by spiritual standards, and views life in the light of eternity. Doing this, he receives whatever comes as from the hand of God. Doing this, his heart is calm in the midst of the storm. Doing this, he rejoices in hope of the glory of God.

When you observe that the fire in your room is getting dull, you do not always put on more coal, but simply stir with the poker; so God often uses the black poker of adversity in order that the flames of devotion may burn more brightly.
