Sacrifice: something that is not natural to give; voluntarily releasing something, doing something you would not normally do, not instinctive; an act of slaughtering an animal or person or surrendering a possession as an offering to God
When we look at Luke 5:27-28 …
27 After this he went out and saw a tax collector named Levi, sitting at the tax booth. And he said to him, “Follow me.” 28 And leaving everything, he rose and followed him.
Matthew had a decision to make. He had to determine if he was going to sacrifice his life and deny himself, or keep his post where he collected taxes from those exporting and importing goods through Capernaum. This could not have been an easy decision. Matthew will have to sacrifice his reputation, comfort, his life, and his job. The bible says, And leaving everything, he rose and followed him.
Sacrifice, is a tough concept. The fact you must sacrifice YOUR desires, your kids, your spouse, job, time, money, etc. Well, in Jeremiah 29, God warns to understand what seems wrong, or different by Him, it is actually for good.
There are 2 big pictures here. This is like a double feature presentation ...
1) Don't think your situation is so off that God cannot help you.
2) Despite your inadequacy God offers opportunities of reconciliation to get your life in order.
Despite us being inadequate He does not disassociate from us. Instead He shows grace mercy, and sovereignty.
