Fourth, God sent His Word to earth for the redemption and reconciliation of the cosmos (Jn. 3.16; 2 Cor. 5.18-20). What Jesus accomplished in His incarnation, death, and resurrection has significance not simply for believers but for the whole world, and not just for the earth but for the entire cosmos and everything in it. A work of reconciliation has been realized which means that now every creature can recover its rightful place before God, even if we can never figure out precisely what that rightful place might be (Eccl. 3:1-11). Indeed, a day is coming when the whole cosmos will be burned up and a new heavens and new earth will be created where righteousness dwells.
Fifth, it has not pleased God for human beings to know everything in the same way that He does (Eccl. 3:11; Deut. 29:29). Through careful study of Scripture and the work of science we may continue to increase our knowledge of the cosmos, but there will always be limits beyond which we simply cannot know and should not try to go (ask Job). We will simply have to learn what we can as we go along, always bearing in mind that there will be mysteries, enigmas, and conundrums that we can’t quite figure out, and always being content for God to be God and us to be mere mortals.Put simply, contra Ken Ham, there is no a priori reason to think that they will not need to be healed and saved just because they are not human. They are God's creations and if they have been created with the intelligence to understand that, then they will be in need of salvation.
