Infinity is a concept that is hard for our finite minds to comprehend. We are limited in many ways (finite), but God is infinite in his nature. He is without limit in his goodness, holiness, knowledge, presence, strength, generosity, kindness, perfection, and love. He is not limited by space and time, and it would take eternity to learn all about him.
“We can imagine—what if all the dust were turned to silver—what if every flower were a ruby—what if every sand in the sea a diamond; yet God can give more than we can imagine, because he is infinite. Oh how rich are they who have the infinite God for their portion! Well might David say, "Surely I have a delightful inheritance!" Psalm 16:6. “
- Thomas Watson
We are such limited creatures that there is no way we could know God apart from him drawing near and making himself known to us. Thanks be to God that he has chosen to give us a glimpse of who he is and what he does through his Word.
How should this affect us?
1. We should fear the Lord
We serve a King who is exalted high above us all. All human knowledge of God is but a drop in the ocean of what he truly is. Knowing this should leave us in awe, an awe that leads to lives of worship and reverence of this infinitely holy God.
2. We should pray earnestly
If God is limitless in power how can we not pray about all of our needs and hopes? He can answer every request, give us the wisdom we need, strengthen our faith, supply us with all we need for life and godliness. But we must ask.
3. We should have a strong faith
If we believe that God is infinitely good and powerful how can we not trust him? God says he is always with us and for us, so we can confidently go through the ups and downs of life with courage. God is so powerful that he is able to take the greatest evil and turn it to our greatest good. (Rom.8:28) How? Because he is “infinite, eternal, and unchangeable, in his being, wisdom, power, holiness, justice, goodness, and truth.” (Westminster Shorter Catechism, Q.4)
His goodness is without limit and his power knows no obstacles. With a God like this our faith should be huge!
4. We should be overcome with joy and thanksgiving
The fact that infinite God would become finite man in order to rescue me; a finite, broken, rebellious, and lost creature is beyond amazing. I should be filled with joy in all circumstances knowing that if he went through all that to save me then I should never doubt that he will also care for me while on this earth.
I should also be filled with constant thankfulness because this marvelous king chose to save a worm (Ps. 22:6 ) like me. He constantly blesses me though I forget him, he continues to help me though I often try to go my own way, and he never stops loving me though I tend to I love myself much more than I love God. But where I fail, God is faithful.
What foundation of comfort can we have in any of God's attributes, were it not for his infiniteness and eternity, though he be "merciful, good, wise, faithful?" What support could there be, if they were perfections belonging to a corruptible God? What hopes of a resurrection to happiness can we have, or of the duration of it, if that God that promised it were not immortal to continue it, as well as powerful to effect it?
