Some things in life are perfect. I can think of three off the top of my head. The Father, the Son and the Holy Spirit.
The law of the LORD is perfect,
refreshing the soul;
The decree of the LORD is trustworthy,
giving wisdom to the simple.
The precepts of the LORD are right,
rejoicing the heart;
The command of the LORD is clear,
enlightening the eye.
The fear of the LORD is pure,
The ordinances of the LORD are true,
all of them just.
They are more precious than gold,
than a heap of purest gold;
Sweeter also than syrup
or honey from the comb.
The greatness of the Lord is his love for us despite our weakness and imperfection.
His care for us is perfect.
