By serving others.
At her death, Dorcas, the woman that Peter previously raised from the dead, was described as being full of good works and acts of charity. "When Peter arrived, they took him to the Upper Room. All the widows beside him weeping and showing tunics and other garments that Dorcas made while she was with them. (Acts 9) Dorcas was beloved by her church and the whole community mourned her loss because she had acted for the benefit of others.
By sharing with others.
Few things reveal the heart better than money. The Bible says, "Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver."
Do these things for the good of others and the GLORY of GOD.
