How do we know God's creation reflects His mercy?

Throughout Scripture, created beings such as birds and whales symbolize the mercy and grace of God towards humanity. As Marvin Stalnaker illustrates, the dove returns to the ark, a picture of Christ, highlighting how creation reflects our need for rest and safety in Him. Similarly, the mention of great whales serves as a prophetic sign related to Christ's death and resurrection, reinforcing that every aspect of creation ultimately points to God's redemptive plan in Christ. This underscores the integral relationship between creation and divine mercy, as every creature, in its own way, preaches the gospel.
