You can check out this pdf to see an illustration of God's work of grace throughout time.  This is an adaptation of some illustrations found in different Bible resources I have come across.  There is no intention of plagiarism or trying to steal someone else's ideas.

I am sharing it because it gave me such a sense of God's love and grace for each one of us that I thought it should be shared.  To keep it from being overwhelming, focus on just one thing, such as Baptism throughout the ages, or how He worked through families, individuals and the Church throughout time.  --Pastor Ben
