This was adapted from a devotional that I read.. What we need is:

When you add this love to your faith, and you begin believing God for others instead of yourself, you believe God to save the lost instead of spending all your time praying for God to take care of your own needs. You care the work of the Lord being done, because the work of the Lord is to help others.

You will care not just in your heart but also in your actions. You will believe God for food to give to the homeless, for clothes to give to the naked. You will believe Him to help you have time to visit the sick. You will believe Him for money to give into His work so that others may be saved. You will care about what is happening and you will want to see His ministry spread throughout the globe!
