The Biblical imperative for giving to God is a tithe. That's a good place to begin in our giving. Sometimes that time may be in prayer. Sometimes that time may be in service to other people, where you become Christ to other people. You help other people.
Love is action.
Love is doing. In these Words of Christ, we are called to love God. Jesus also says we are called to love each other as we love ourselves. How you love yourself is how you can love other people. If you do not love yourself, you do not have a lot to offer, in the way of love, to other people.
