Do you see a need in Ethiopia? Then work towards meeting that need.
Is there a need for shut-ins to receive meals? Then deliver meals to them.
Do you recognize a need among orphans in Haiti? Then start helping the orphans.
Are there needs in a local food pantry? Then spend your time helping them.
Are there elderly people in your area who need help? Then help them.
If you see a need, then work towards meeting that need. Invite others to work with you, but don’t wait for them before you start obeying God.
If God is not calling you or gifting you to meet that need, then he will make that clear. Often, though, he reveals your calling and gifting in the midst of you serving others.
I cannot tell you exactly how God is calling you or how God has gifted you. I can tell you one thing that I know with complete certainty. God is NOT calling you or gifting you to do nothing or to only do for those who can love and serve you in return. God is NOT calling you or gifting you only to care for your friends or other believers.
Look around you. Do you see a need? If yes, then start working towards meeting that need. If no, then look again, because you are deceiving yourself. If you still can’t find a need, then join one of the people linked to above in serving others.
