When we are born, we are in our most selfish condition, by necessity. For survival, we must cry out for help to live. That is why a baby cries for food, and to be changed. They can do nothing for themselves.
As we grow, we must learn to share our toys, food, and time. To fail to do so causes problems. Children still think only of themselves, and get in fights and some even become bullies. Hopefully, we grow out of this, but some don't.
As adults, those who learn to share, and learn to think of others first can find love. For love is giving of yourself, for the good of others. We are meant to grow into this, and if we fail to it leads to divorce, suffering, war, and a host of other civil problems.
Parenthood is the greatest sacrifice of love. To love, provide, and care for a child. Just as you were when you were born, helpless and needy by design. It comes full circle.
Faith by design is like this too. We first come to God wanting things. God being a good Father, knows our needs and is happy to provide them. He wants us to raise our arms to him and ask "Pick me up". He lives for that. But we must grow. We must take on his fatherly ways to be called his children. We must grow more giving, and more compassionate. To see in other's eyes, and understand where they are in life. To help them because we love them, just as God loves us. To this end we were born, to be like the Father.
