I was referring to your bringing up Matthew 19 (the story about rich young ruler) as an example for us to follow in regards to finances.
You said: „God does demand that we sacrifice our earnings to him; and not just part, but all of it. Just read
Matthew 19:16-22. Our Lord is Lord over every single aspect of our lives, and this includes the entirety of our money. If he wants us to do something with it, it is his choice, not ours. As my pastor often puts it, ‘The Lord is either Lord of everything or Lord of nothing.’“
I say: no, God does not demand anything from us. The Law demanded – grace supplies – as one of the great preachers put it. God chose to share everything with us. He owns everything but He does NOT demand to give anything. If we think that it is God who „demands“ – it only shows we still have the Law mentality instead of grace mentality. Zaccheus (which Jesus met in Luke 19, after He met rich young ruler) was ready to give out of pure heart and Jesus did not tell him what He told previously to rich young ruler! Why He didn't? Because Zaccheus was free from legalistic mentality.
Unless it is Holy Spirit who prompts us to give out of love – it is not acceptable in God's eyes!!
My overall point is that tithing was part of the Law and we are to be „dead to the Law“, as Paul says! Abram was future father of fleshly children, those who are „of the Law“ (Galatians 4:22-26). Abram's life and actions were a prophetic picture of what his future fleshly children will do (give tithes). I emphasize: Abram gave tithe – NOT Abraham!! Abram gave tithe in the 14th chapter of Genesis - before he even made a covenant with God (15th chapter)!! We are in the covenant with God already, are we not? So IF we recognize today that we are in the covenant with God (in Jesus Christ) – why we would go back, to the pre-covenant actions? Why would we follow someone's actions (tithing) when the person who did it (Abram) was in completely different position from ours when he tithed!? We are called to discern from God's Word what is for us, and what is not (because it is already fulfilled or obsolete).
Abram only later become AbraHAM (17th chapter) - which made him father of many nations, our „father by faith“! Christians has nothing to do with Abram and what He did!!! We are AbraHAM's children! What Abram did before he became Abraham is well behind us, as the cross is behind us, as cross is the reality which accomplished our complete salvation and well-being and blessings once and for all!!! Melchisedek's giving bread and wine prophesies about Jesus' body and blood! How many times Jesus gave it? Once and for all! So, Christians are sons of Abraham, sons of covenant of faith, by which we are blessed (Galatians 3:14!!). Even more than that: we are „sons of God in Jesus Christ“ (not the „sons of Jacob“ that Malachi refers to!)We are blessed NOT because what we do (give, serve... whatever) but because of what Jesus has done for us! (Ephesians 1:3).
That's why our giving has to be out of pure heart, out of love for neighbours in need and also to possibly sustain those who, because of commiting themselves exclusively to preaching the Gospel, chose not to take regular jobs. But I am against pastors and ministers getting money from members by abusing scriptures, by twisting and falsely interpreting examples from the Bible! God does not want His children to be abused by no one! He wants us to respect His Word, so we won't be easy pray of those who twist His word (intenionally or not)!
Also, today all christians are all priests and kings, „royal priesthood“ (1st Peter). There is no distinction between laity and priesthood any more! In the OT period tithe was intended for sustenance of the priests and levites (helpers to the priests). Today everyone in the body of Christ is supposed to serve („each one according to the gift of grace God gave him“) because we all are kings and priests, and we all have only One KING and HIGH PRIEST (Jesus Christ, our Melchisedek). He would be THE only one entitled to receive tithe, if He were on earth. (Because Abram gave it to Him personally, not to any mediator, representative etc.) That's why New Testament brings the concept of „sharing“ instead of giving to some special class (pastors). Sharing is emphasized by introducing the concept of „body“ which never existed prior to the New Testament! When I eat –my whole body is nourished, not just my stomac, my head or whatever. When there is imbalance in the body of Christ, something must be wrong with the sharing of food and care!
God bless you my young brother in your search for Truth about any subject God will reveal to you.
