The Bible talks about God’s love for mankind, and the sacrifice He made when He offered His only begotten Son to die for everyone. The same way, a Christian who has already accepted Christ as His personal Savior needs to show the same love for others. How?
In the Epistle of James, he said having faith in a loving God is good, unfortunately, people who still do not know Christ won’t be able to comprehend it. The only way for them to understand God’s love is for believers to show it through their actions. That is why helping others is a duty that should always be evident in the life of a Christian.
Just like what the good Samaritan did with his neighbor, we are expected to give what we can to others to help them. Otherwise, we are no different from those who have not yet trusted Christ as their Savior.
