Hebrews 11:1 states (in my paraphrased translation), that living by faith consist of being convinced of things we cannot see. That must not be too easy. How do I know you ask? Abraham is listed in this section of the scriptures as a hero of living this way, that is by faith. However, a careful scan of his life in the pages of scriptures indicates he struggled with being convinced of the things he could not see. On the other side of the coin, he did not seem to have this issue when he could visually see the issue.
The book of Genesis records several scenarios involving Abraham taking some type of action in response to various situations. It appears that when Abraham needed to act on something he could see, there was little to no hesitation. For example. When Lot was captured in Sodom, Abraham had an army of servants ready in a heartbeat. When Abraham was told by God to circumcise his household, boom, it was done. When Sarah told Abraham to take Hagar as a wife in order to have children, there does not appear to be any hesitation on Abraham’s part to do so. When the angels and God appear to Abraham to let him know what God is going to do to Sodom, Abraham does not hesitate to intercede for Lot’s sake. Get the picture.
Now go back to Genesis 17 with me. God tells Abraham, that he and Sarah are going to have a baby, what happens? Abraham laughs himself silly. He could not see this happening. It would happen by faith and not sight, and Abraham struggled.
We must guard ourselves from becoming a “by sight” Christian. History would tell us, the best of us have difficulty responding to God’s promises we cannot see. Walk by sight! No problem. Walk by faith! Now that is a problem. Let’s not leave the promises of God sitting on the table due to being “a by sight” Christian.
