Amadeus2,
Yes, the ot context was Malachi chastising the priests for robbing God.
How can we make this relevant to us today, or what would God say to us through this passage?
Well it wouldn't be about tithing because that system was as OT as sacrifices, burnt offerings and the jubilee years. Unless you think God also wants us not to work every 7 years, to make burnt offerings, and to redistribute all property every 50 years etc...
Perhaps the modern message is that God will judge his people who steal from widows and the poor, and this is as if you are stealing from God. Instead we should help and support the poor, for when you give to the poor you give to God.
But even more important than providing material help to the materially poor is providing what we have from God spiritually to those who are spiritually hungry and thirsty:
"Blessed are they which do hunger and thirst after righteousness: for they shall be filled." Matt 5:6
What do we have to give to others that is better than material riches? If I were like Peter here, could I do what Peter did?
"Then Peter said, Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk." Acts 3:6
The lame man was healed physically, but should we not have something more or better to offer those who are hungry and thirsty for God's righteousness? Are we not overflowing with the things of God, or if we are not, should we not be so overflowing so as to share as Jesus shared, directly or indirectly?
Mat 9:20 And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment:
Mat 9:21 For she said within herself, If I may but touch his garment, I shall be whole.
Mat 9:22 But Jesus turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour.
Money is hardly what people should have on the top of their prayer list. My wife and I always give 10% plus, but is that not simply and only part of the alms of Matthew 6? There is more to alms than that and there is more to Jesus' words in that chapter as in prayer and fasting...
And then again:
"And t
hough I bestow all my goods to feed the poor, and though I give my body to be burned,
and have not charity, it profiteth me nothing." I Cor 13:3
