There are times when we find ourselves doubting that God really cares for about us…that He REALLY does love us personally. One of the SMALL indications He has given to reassure us is the incredible variety He invested in His creation! And God makes it pretty clear that these created beings are for us. Genesis 1:27-30. Also, the very fact that He so cares for these creatures is a huge reminder to us that He cares infinitely more for us, His children! Check out Psalm 104:24-34 (ESV).
24 O Lord, how manifold are your works!
In wisdom have you made them all;
the earth is full of your creatures.
25 Here is the sea, great and wide,
which teems with creatures innumerable,
living things both small and great.
26 There go the ships,
and Leviathan, which you formed to play in it.[a]
27 These all look to you,
to give them their food in due season.
28 When you give it to them, they gather it up;
when you open your hand, they are filled with good things.
29 When you hide your face, they are dismayed;
when you take away their breath, they die
and return to their dust.
30 When you send forth your Spirit,[b] they are created,
and you renew the face of the ground.
31 May the glory of the Lord endure forever;
may the Lord rejoice in his works,
32 who looks on the earth and it trembles,
who touches the mountains and they smoke!
33 I will sing to the Lord as long as I live;
I will sing praise to my God while I have being.
34 May my meditation be pleasing to him,
for I rejoice in the Lord.
