It is written:
“These all wait for You, That You may give them their food in due season. 28 What You give them they gather in; You open Your hand, they are filled with good. 29 You hide Your face, they are troubled; You take away their breath, THEY DIE and return to their dust. 30 You send forth Your Spirit, THEY ARE CREATED; And You RENEW THE FACE OF THE EARTH.” (Psalm 104:27-30)
The Bible here describes the life and death of animals, followed (at some point in the future) by their resurrection. The famous Bible commentator, Adam Clarke, wrote of this passage:
“Do not these words plainly imply a resurrection of the bodies which have died, been dissolved, or turned to dust? And is not the brute creation principally intended here? Is it not on this account it is said, Psa 104:31, “the glory of the Lord shall endure for ever, (לעולם leolam),” to be manifest in those times which are secret, when Jehovah himself shall rejoice in his works; when the brute creation shall be delivered from the bondage of its corruption? See the notes on Rom 8:19-23.” (Clarke’s Commentary On The Bible, E-Sword Edition)
The Bible seems to suggest that animals will populate the new heavens and the new earth.
Whatever Heaven is like, God wants you to be there (Ezekiel 18:23)! Have you been added to God’s church (Acts 2:47)? If not, then as a believer repent of your sins and be baptized into Christ today (Acts 2:37-38). If you are an erring member, then turn back to Him today in repentance and prayer (1 John 1:9).
