What to know Some Muslims have been taught that God would never make a covenant, promise, or commitment to mankind: to make a promise to his creation is beneath Him. Others believe that while he may make a promise, it's disrespectful to assume He'll keep it. God is considered too great to keep His word. Many, applying this to judgment day, will tell you that in the end, it's all about Qadar (fate) and God's mercy. Even the scales on judgment day, and keeping the pillars of Islam, means nothing.
What does this mean? In some senses, Muslims are resisting the concept that any law or code of morality exists that binds God to anything: even His own law and morality.
Revelation 4:8 says that day and night, the living creatures never stop saying, "Holy, holy, holy..." In Islam, rather than this refrain, it could be said that we see a constant exaltation of God's power...even at the expense of his other characteristics. In the Gospel, we see God's justice, love, mercy, power, and holiness expressed in perfect unity. The Gospel of Jesus upholds every quality of God, while distorting and lessening nothing. For that reason alone, we shouldn't be surprised to find that theologies that exist in denial of the Gospel will fail to represent the nature of God. What to say
Returning to the story of Nuh...If your friend struggles over God's promise to mankind, don't feel pressure to convince them from one story alone. We'll revisit the topic in the story of Ibrahim in more depth. For now, listen as your friend begins to articulate their beliefs, and pray for them, as they hold these up against the light of God's Word. If you feel led to more clearly state your belief about God's willingness to not only make a promise, but keep it, pause to read Matthew 7:7-11. Followers of Jesus believe that anything good that a human is capable of originates with God. We are never greater or higher than he is. To that end...if humans, who al-Masih says are "evil," are capable of upholding a commitment, isn't it disrespectful to believe that God isn't able? Consider also James 1:16-17, together with 1 John 1:5 and 2 Corinthians 1:20. God doesn't fulfill his word because he is bound to something that's beneath him. He fulfills his word because doing so is an extension of his character. In John 8:43-45, we see that Shaytan (Satan) is a liar: he speaks, but because of his character and being, we can't trust his words to be true. God is unlike Shaytan. When he speaks, we can trust his words. Read Isaiah 46:8-11 together, along with Numbers 23:19 and Isaiah 14:24. What attributes of God are we exalting when we believe him that he does what he says?
