Genesis 2:25 tells us that though Adam and Eve were naked in the Garden of Eden, they were not ashamed. I believe that in addition to indicating they were without clothes, this scripture also implies they were totally open and honest with each other—not hiding behind any masks, not playing any games. They were free to be themselves because they had no sense of shame. Once they had sinned, however, they hid themselves (see Genesis 3:6-8).
If not for the work Jesus did on the cross, all of us would have to live with the overwhelming shame of sin. But because of His sacrifice, mankind has the opportunity to enjoy perfect freedom with one another and with God.
Unfortunately, most of us still live with the burden of shame, even though the Word of God promises us and assures us that we can be free of it (see Isaiah 61:7).
God can deliver you from shame. Pray and ask Him to set you free from the shame that tries to build up within you.
