If you don't kill your baby, you risk your life. So when Moses' parents decide they are not going to drown Moses in the Nile River but hide him, they are risking their lives. We will not kill our son out of fear for our own lives. Fear of death will not control us. By faith Moses .
Faith is the assurance of things hoped for.
Faith frees us for this kind of radical courage and risk-taking and love because it is the assurance that what God promises to those who die in the path of love is better than what the world promises those who shun risk and save themselves. More simply, faith in God's promises frees us from the fear of death and makes us brave in the risks of love. There's a minor point here as well as this main one. It's important for all of us who want our lives to be on the cutting edge where there are risks and dangers and great crises and great needs. It's a point of realism and balance.
