If you aspire to practice Christianaity, the Bible is your source. The homeless are just one face of the suffering of humankind. Christ himself said 'Whoever is first will be last, and whoever is last will be first.' There's not really much more to say. Helping the homeless, the poor, or anyone in need can be very rewarding. Unfortunately, our human nature often leads us to do it for the wrong reasons. I've seen this in myself and I accept it as part of my sinful nature.
God has dealt with me a lot about my humility or lack thereof. That's another lesson Christ drummed into us, humility. Helping people in this way has taught me to humble myself in a way that I never have. I've learned that I'm no better than those I'm trying to help. In the eyes of God, that person is a soul he created, and his love for that person is as great as his love for me.
The Greatest Commandment
"Teacher, which is the great commandment in the Law?" And he said to him, "You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself.
The Parable of the Good Samaritan
Now an expert in religious law stood up to test Jesus, saying, “Teacher, what must I do to inherit eternal life?” He said to him, “What is written in the law? How do you understand it?”The expert answered, “Love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind, and love your neighbor as yourself.” Jesus said to him, “You have answered correctly; do this, and you will live.”
But the expert, wanting to justify himself, said to Jesus, “And who is my neighbor?” Jesus replied, “A man was going down from Jerusalem to Jericho, and fell into the hands of robbers, who stripped him, beat him up, and went off, leaving him half dead. Now by chance a priest was going down that road, but when he saw the injured man he passed by on the other side. So too a Levite, when he came up to the place and saw him, passed by on the other side. But a Samaritan who was traveling came to where the injured man was, and when he saw him, he felt compassion for him. He went up to him and bandaged his wounds, pouring oil and wine on them. Then he put him on his own animal, brought him to an inn, and took care of him. The next day he took out two silver coins and gave them to the innkeeper, saying, ‘Take care of him, and whatever else you spend, I will repay you when I come back this way.’ Which of these three do you think became a neighbor to the man who fell into the hands of the robbers?” The expert in religious law said, “The one who showed mercy to him.” So Jesus said to him, “Go and do the same.”
When 1 he saw the crowds, he went up the mountain. 2 After he sat down his disciples came to him. Then he began to teach them by saying:
Blessed are the poor in spirit, for the kingdom of heaven belongs to them.
Blessed are those who mourn, for they will be comforted.
Blessed are the meek, for they will inherit the earth.
Blessed are those who hunger and thirst for righteousness, for they will be satisfied.
Blessed are the merciful, for they will be shown mercy.
Blessed are the pure in heart, for they will see God.
Blessed are the peacemakers, for they will be called the children of God.
Blessed are those who are persecuted for righteousness, for the kingdom of heaven belongs to them.
Blessed are you when people 11 insult you and persecute you and say all kinds of evil things about you falsely on account of me. Rejoice and be glad because your reward is great in heaven, for they persecuted the prophets before you in the same way.
