God passes his blessings from one generation to the next. Deuteronomy 7:9 in the ESV version says, "Know therefore that the Lord your God is God, the faithful God, who keeps covenant and steadfast love with those who love him and keep his commandments to a thousand generations.”
Following the way of the cross makes you a blessing to your family, your friends, even people who don't know you personally. And it gives you a spiritual legacy. Your children, their children, and on through your family line will be blessed by the life you are living today. You are part maybe the beginning of a generational storyline that God is writing.
And it's not just physical children who will carry your favor and your blessings forward. Spiritual mothers and fathers have many, many children. God calls each of us to grow up to father and mother those who come after us. Life is not about what you can get for yourself. Life is about you creating blessings for all the lives you influence today and on down through the generations to come.
