Feast and Follow with Knollwood Knollwood Presbyterian Church

Today, we finish up last week's message by looking now at how personally involved God is in judgment as well as blessing.

For a God who never gets hungry, He sure eats a lot. This isn't because God has been dishonest with us about His needs. God doesn't get hungry or need anything from us. Psalm 50:12-13 put it this way "If I were hungry, I would not tell you, for the world and its fullness are mine. Do I eat the flesh of bulls or drink the blood of goats?" The expected answer is, "No." God doesn't need to eat something because He doesn't have a body. Even if He did need to eat, He wouldn't be waiting around for us to feed Him because He already owns everything in the earth. So why is He eating here? He doesn't need it. This is meant to draw our attention when God does something He doesn't have to do. It means that God is making a point. He doesn't want us to walk away from this passage to say that God has a taste for beef. He is showing Abraham, and us, something special by coming down to eat with Abraham. We are only going to get to our first point today: God is personally involved in blessing and judgment. In our tour of Genesis, I want us to stare at this point for a minute, namely, the imminence of God, His closeness, His intimacy. This was a point that I had missed in my initial study of this passage, so I greatly owe Dr. Allen Ross for pointing me in this direction for this sermon. It is easy to miss the closeness and intimacy with God in Genesis so far because of all the big things He does. He sets up the world, and then He floods the whole thing. He separates all the peoples by introducing different languages. He brings a plague on all of Egypt. He helps Abraham defeat close to half a dozen kingdoms in battle. He is promising that Abraham will have descendants outnumbering the stars! In the next chapter, He turns the green, fertile fields of Sodom into the Dead Sea with flaming brimstone launched from heaven! And then there’s this chapter where He stops by for lunch. 

Symbols are important things. They aren't just images that are nice to have. They are essential to our memory. We have rings for marriage because they are meant to remind us to stay faithful. I don't need reminding that I am married; I need reminding that that marriage makes a difference in how I live. I am no longer just me. I am married to my wife. That doesn't just change what I do in any given bedroom. It changes how I take out the trash, how I spend money, and it even changes things for descendants. My children are greatly affected by my covenant with my wife. Their lives are different because of it. 
Today, we are going to be looking at a symbol for a covenant that has effect even unto today, circumcision. Modern life has made this awkward to talk about, but I think precisely because it is such an intimate symbol, it really strikes a cord that this is what was used by God in the Old Testament. Now, just to clarify at the start, circumcision is not required today (Acts 15). You do not need to undergo this process to be saved. There is nothing that saves you but the blood of Christ. 
That being said, we will see that there are some elements of this covenant that continue. We will see that though this promise is made to Abraham and Isaac, Ishmael will receive the sign, too. We will see that God works in households, not just individuals. Circumcision gives blessing to all in that covenant, but the full enjoyment of the blessings of that covenant are for those who are circumcised in heart and thus obey the will of God (Redd, 142 *Covenant Theology*).  
Today we will explore our two points: God provides a sign of His covenant and We are called to apply and remember His sign.  

What does it mean to believe? When we tell people that they need to "believe in Jesus," what are we actually telling them? This is a key question to answer, because whatever it means to believe is how Abram was counted as righteous before God. And according to Paul, whatever it means to believe in Jesus is how *we* are counted righteous as well, is how we get to heaven—or not. This passage is mentioned many times in the New Testament, so if they saw it as important, we must see it as important. I will give you the answer up front, and then we will develop it as we go. To believe, simply enough, is to see something as dependable (Ross, 310) or "place trust in someone with confidence..." (Matthews, 166). To believe in God is to see Him as dependable and then live in light of that (Ross, 310)!  
This should be a pretty understandable concept because W]we depend on things all the time. Whenever a dad is loading up a trailer and needs to secure the load, what does he reach for? The ratchet straps! After expertly crisscrossing the trailer, tightening it down, what is he practically *required* to say after giving it a tap? "That's not going anywhere." Why does he say that (every time)? It is because he sees those straps as dependable. While the rest of us nervously look back at the load over each bounce, eyes are forward because he knows what those straps will do. Do you depend on God to at least the same degree your dad depends on those ratchet straps? If not, I encourage you to listen in to what Genesis 15 has to say. 
We will unpack this more as we uncover our two points today:  God promises what only He can deliver and God gives signs so we won't forget His promises.

​Last week we discussed how Abram doesn't have to fight in order to obtain the blessing of the Lord, but we did end it with the fact that Abram doesn't have to be a doormat and is to fight for what the Lord calls him to. Here in chapter 14, we see that call come. As one scholar put it, "Sometimes it requires more faith to take action than to remain passive" (Waltke, 237). Sometimes you need to commit to action, and fighting for the protection of his family calls Abram to arms. But as we will note here, Abram isn't saved by the sword but by the Lord and acts accordingly in his tithe to this mysterious Melchizedek. So let's dive into this passage looking at our two points today: Fight the Lord's battles when called, and Win or "lose," return to the Lord His due. The nature of our conflicts and the weapons we use today as Christians are different, but there is much that we can learn and take comfort in in this passage.
