Is Tithing For Today?

Giving is a predominant theme throughout the word of God. God, Himself, is the Supreme Giver. "For God so loved the world that He gave His only begotten Son..." Through the ages, His people have been taught to give back to Him by giving to His cause and by sharing with others. Though the practice of tithing, or giving a tenth of one's property back to God, predates the Mosaic law, it was made a commandment unto the Israelites. Congregations of Christians are taught to collectively treasure up a portion of what they have been given each first day of the week (1 Corinthians 16:1-2). Is this the same thing as tithing? Are Christians commanded to tithe under the new covenant and if not, what are we to give to the local church?
