He loves us.
God made every one of us (that includes you!) in His likeness. We’re made to live in a loving relationship with Him, and to reflect His character as we live our lives. It’s what we’re literally designed for.
This is all for God’s glory. That means loving Him, trusting Him, obeying Him and treasuring Him above all things – but out of joy, not duty. He created each of us to put Him first in all things and to enjoy Him forever, with all of the amazing things He gives us.
