But the words “it was counted to him” were not written for his sake alone,  but for ours also. It will be counted to us who believe in him who raised from the dead Jesus our Lord, (ESV)
There is a reason why the Bible is the best-selling book of all history. It is not because it is full of great historical accounts, although it has plenty of that. It is not because it contains great poetry, even though it has a lot of that as well. It has great instruction as well. Yet, that is not the reason it is the best selling book of all time. It is the greatest book because it is truth!
The truth of Scripture is for every generation. The words that we find which applied to Abraham applied to Paul, and also to us. As the Apostle Paul tells us in this verse, "the words "it was counted to him" were not written for his sake alone, but for ours also." Abraham was credited with God's righteousness by his faith. The same is true for us.
Abraham did not know the Lord Jesus. He had no idea that there would be a Messiah who would come and redeem all of mankind. What he did know is the one who raised Jesus from the dead. Abraham believed God. We also believe God who raised Jesus from the dead. Our faith is in exactly the same God.
This great book that we have speaks to all generations. In fact, the purpose of the Bible is to reveal God to man. No other book can claim such a purpose. When you open your Bible be in awe of the fact that every word that is written is for you. It may have been written thousands of years ago, but the words are just as true and applicable to your life as they were then.
Do you have faith in God? It is the same faith in the same God that Abraham had. You belong to a wonderful heritage.
