Tithing is not only important for the advancement of God’s kingdom, it is imperative, for no spiritual ministry can function without physical means. 
        Although not giving directly to the hands of God, a person is giving to the work of the Lord when tithing to a local church that uses those funds as a means of ministering to others and being the hands of Christ. A person may also give to the work of the Lord through additional giving, such as donating to another Christian ministry that serves the Lord and shares the Gospel, or when giving directly to a fellow man in need.
        We truly live out the teachings of Jesus when we give as greatly as we possibly can.
        It is even not necessarily the amount a person gives, but the amount that a person has left over after giving, that equates sacrifice in giving.
        Jesus taught His disciples about the value of true giving and the fact that little is much when God is in it, when He showed them that a poor widow giving a small amount, which was her all, had given so much more than others who had given a higher amount.  “And He looked up, and saw the rich men casting their gifts into the treasury, And he saw also a certain poor widow casting in thither two mites. And he said, Of a truth I say unto you, that this poor widow hath cast in more than they all: For all these have of their abundance cast in unto the offerings of God: but she of her penury hath cast in all the living that she had.” (Luke 21:1-4)
        But, as important as it is to give to God, and to give as greatly as we possibly can, Jesus placed an even higher importance on being right with others.
        According to Jesus,  far worse than what might be called 'robbing God' of tithes is when a person's repeated and unrepented of sin against others robs others of their joy and peace.
        Christ does not say to not offer tithes, but rather to make things right with others before making an offering.
        “Ye have heard that it was said by them of old time, Thou shalt not kill, and whosoever shall kill shall be in danger of the judgment: But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire. Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee; Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.”  (Matthew 5:21-24)
        “Jesus tells us to leave our offering and make things right with a brother before we can worship,” said Dr. Adrian Rogers. “No one can be right with God and consciously wrong with his brother. Now, notice that Jesus doesn’t say that you need to leave your tithe and go reconcile with a brother if you have something against him. Here, Jesus is saying that you need to get things right with a brother who has something against you. Before you sing, before you pray, before you teach, before you give, before you worship, the Bible says you are first to be reconciled to your brother. There is no offering on earth that can substitute for getting right with your brother. As far as you know, is there someone who is harboring ill feelings toward you? Then, the Lord says, ‘Leave it there and go get it right.’ Before you do anything else, right now, this very minute, ask God to show you if there is anyone with whom you need to reconcile. Then, go and do it my friend.”
        “In Matthew 5:23-24, Jesus was emphatic about the importance of getting right with those you have offended,” said Gregory Frizzell. ‘Therefore, if you bring your gift to the altar, and there remember that your brother has something against you, leave your gift before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift.’ In other words, Christ was saying, ‘Don’t approach God until you first get right with those you have offended.’ ”
        “Restoring broken fellowship is so important,” said Rick Warren, “Jesus commanded that it even take priority over group worship. He said, ‘If you enter your place of worship and are about to make an offering, but you suddenly remember a grudge a friend has against you, abandon your offering, leave immediately, go to this friend and make things right. Then and only then, come back and work things out with God.’ When fellowship is strained or broken, plan a peace conference immediately. Delay only deepens resentment and makes matters worse. In conflict, time heals nothing; it causes hurts to fester.”
        “The Bible clearly encourages us to be quick to apologize – even to leave our gift at the altar and first go and be reconciled to our brother or sister (Matthew 5:23-24),” said Ron Hutchcraft. “It’s part of carrying out our Lord’s orders in Romans 12:18: ‘As far as it depends on you, live at peace with everyone.’ Ask God to use your two little words – ‘I’m sorry’ – in a really powerful way. Sometimes, two little words are the beginning of a very big breakthrough.”
        “Jesus tells us to stop praying for forgiveness until we’ve made things right,” said Chuck Swindoll. “When you have been the cause of an offense – that is, when you are the offender, have the heart of a servant. Stop, go, reconcile, and then return. Confess your sins one to another. Only pride is stopping you.”
        “He hath showed thee, O man, what is good; and what doth the LORD require of thee, but to do justly, and to love mercy, and to walk humbly with thy God.” (Micah 6:8)
