The Bible says that God loves his children with unfailing, everlasting love. He values, loves and accepts them as a father does his infant child, when he has done nothing to deserve it. It also says nothing can separate us from God's love ... maybe, even, ourselves.
The Bible also says that God has given gifted men to prepare his family for significant work. He has given marching orders to make disciples of all peoples, all over the world. And he says that his body will grow when each part does its work properly.
On one hand, there is no need for us to do anything. We need only accept this rest. On the other hand, there is clearly an expectation that God's children will take action.
Like so many things, the answer lies in the heart. God has poured out his love into our hearts. He changes our motivations. He changes our want-to's.
Love gives birth to love; love gives birth to loving action. God loves us. So, we love him in return. And we give love to others. And we act in love to God and others.
