1. They describe how God is not like us.
His incommunicable attributes belong to him alone. They are true of him and no other. His immeasurability, incomprehensibility, self-existence, self-sufficiency, eternality, immutability, omnipresence, omniscience, omnipotence and sovereignty should elicit from us, “Who is like you, O Lord, among the gods? Who is like you, majestic in holiness, awesome in glorious deeds, doing wonders?” (Ex 15:11)
2. They know no limits.
Everything that is true about God’s nature and character is infinitely true. He is infinitely creative, infinitely sustaining, unlimited by time. God knows no limits on his presence, knowledge, power, and authority.
3. They show us our limits.
When we contemplate God’s limitlessness, we see our own limits more clearly. We are better able to recognize where we are attempting to play God in a relationship or circumstance. Humbled by comparison, we reorient our hearts toward submission.
4. They are not ours to imitate.
We can and should imitate God’s communicable attributes. By the power of the Spirit we can learn to be merciful, loving, long-suffering and gracious. But we must not covet or mimic his incommunicable attributes. We are not designed for omniscience. We are not entitled to omnipotence. We must not aspire to self-sufficiency. To do so is to take what is his and to invite disaster.
5. They challenge our understanding.
Because God is infinite and we are finite, our ability to know him is limited. We don’t know anything or anyone that is unlimited, so it is difficult to find comparison points that can help us understand his attributes. They are, however, able to be understood sufficiently through the Bible. All knowledge of him that is necessary for life and godliness can be found there, and is worth laboring to understand.
