God saw His creation literally devouring itself and sent His Son to be born, live, die, and rise again so that anyone who identified with Him would be free from these deadly desires and able to live forever in love. This phrase tells us a lot about what it means to be His people. Most of us know that we should do good deeds. We remember the parable of the Last Judgement with its good sheep and bad goats. The truth is that He wants more from us.
Zeal implies an enthusiasm and eagerness that are powered by love.
If we are zealous to do good deeds which truly help people, then we are not doing them grudgingly out of a sense of obligation, but out of love - love for our God and for fellow human beings. This love urges us to do anything that we can to help someone else. There is no question that this is a difficult task. It is an olympian effort to sustain this type of fervor every minute of every day. But if we do have the slightest zeal and love for God, we will realize our shortcomings and want to make things right with Him and with others.
