The fact that we have anything to give, even a 10% tithe, is all because of grace. We are under grace and not under law. We can serve the law through grace with no condemnation if we fail it in any way. That is the beauty of God's grace. Grace doesn't do away with tithing or the giving of offerings, and if you think it does then you are mistaken and you don't know the scriptures. God calls the believer to be member of God's body, the church. Every believer is called to serve and participate in a local church. If you do not have a local church, you need to find one because you have a calling to do so. You just can't be an independent believer with no local church, no edification, no teaching and no fellowship with others. That local church you give your tithe to is the one God has called you to be a joint participant. You serve others there, you minister and pray for one another there, you forgive one another, love one another, build one another up, you worship God in Spirit and truth with one another, your kindly affectionate to one another, your kind and tender hearted to each other and you participate in the work of the ministry with one another and you give to that work with your tithes and offerings. That's Bible, that's being a Christian and that is what the body of Christ is all about. Christ is the head of His body and if you are not part of a local church that is serving God then you are detached from the head, Jesus Christ.
