So God created mankind in his own image, in the image of God he created them; male and female he created them.
– Genesis 1:27
This fundamental statement that is found in nearly all major world religions is far more important than we've treated it.
Image here does not mean appearance because Scripture is very clear about God being invisible. What it does mean is identity. So, if we're made in God's image, or identity, what does that mean? God is Love. We are made in the image of Love. And Love is WAY more than just a sentiment or feeling.
That you are made in God's invisible image means that you affect me in ways very similar to how God affects me: spiritually, invisibly, subtly, powerfully. You are important. You are important to how those around you make it through life.
When we think and act like we are not important, our importance doesn't just go away; we end up making very important mistakes. They're important because they hurt other important people.
So, often we identify ourselves more with our mistakes and the mistakes done to us rather than our importance. This is backwards! The only reason our mistakes are important is because we are, first of all, divinely important.
Allowing time for God to speak to us and spiritually/invisibly move in our hearts regularly is how we come to truly and humbly understand our importance and significance.
Jesus answered them, “Is it not written in your Law, ‘I have said you are “gods”’? If he called them ‘gods,’ to whom the word of God came—and Scripture cannot be set aside— what about the one whom the Father set apart as his very own and sent into the world? Why then do you accuse me of blasphemy because I said, ‘I am God’s Son’?
– Jesus, John 10:34-36
