"The LORD will command the blessing on you in your barns and in all that you undertake. And he will bless you in the land that the LORD your God is giving you." (ESV)
"The LORD will guarantee a blessing on everything you do and will fill your storehouses with grain. The LORD your God will bless you in the land he is giving you." (NLT)
The Lord says that He will command that you be blessed! What is that blessing? It is to prosper and have all the blessings that God blessed Adam, Noah, Abraham with, and now added in our time all the blessings of Jesus.
Let's break this scripture down. When God said "in your barns" He meant in your work, for the barn was where the Israelites held their working tools and housed their most important commodities for selling, which was their livestock. Today, in our culture because many are no longer farmers, "in your barns" means in your offices, at your desks, in your car, wherever your work is located.
That is good enough in itself, but He goes on to guarantee that you will be blessed in ALL that you undertake. Hey, I didn't write this, the Lord did. So what this means is whatever you set out to do, whether it be writing a book or music, or perhaps you are an artist of painting, selling products on the side, etc., God promises you that He will bless it to prosper.
Now our cup is really overflowing, but God doesn't stop there. He goes on to say that He will bless you in the land He is giving you. Don't miss it here. He didn't say "land He gave you." He said "land He is giving you." Do you see it? It isn't a one time only gift in the past tense of gave. It is a continual present tense of giving. God is continually giving to us. He will never stop. Take it. It blesses Him when you do for He never runs out of something to give.
Now you may be saying, "Sandy, that was the Old Testament and they had to obey all the laws in order to obtain that blessing." Yes, in the OT, the Israelites had to obey the Law on their own merits to receive God's blessings, but under the New Covenant, which is far superior to the Old (Hebrews 8:6, 13), Jesus obeyed the Law for us. He took the Laws and paid every requirement for it upon the Cross (Colossians 2:14) so that we could stand free and receive all the blessings of God because of what He has done and not because of anything we could ever do. We have everything in Christ no matter what the world is doing. Our part is only to receive it.
May God bless you according to His Word!
Sandy
