Have an Undivided Heart!

1 Chronicles 12:33 Of Zebulun, there were 50,000 who went out in the army, who could draw up in battle formation with all kinds of weapons of war and helped David with an undivided heart.

Colossians 3:23-25 Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.

50,000 soldiers from the tribe of Zebulun served in David’s army with UNDIVIDED (some translations: “not double-hearted”) hearts. Can you imagine a skilled army with this level of loyalty and devotion?

An undivided heart is one of the most powerful things on earth. Singleness of purpose will flow from the life of a person whose heart is undivided. Couples whose hearts are devoted to the Lord this way will preserve their marriages, no matter how difficult their issues and problems become. Intercessors whose hearts are filled with a single purpose will ultimately demolish terrible strongholds. Missionaries with vision and absolute loyalty, will be able to take entire nations for Christ. One woman will pour out ointment worth a year’s salary on her savior’s head. An undivided heart is one of the most powerful things on earth.

Yeshua (Jesus) inspires and empowers undivided hearts. If you really know him well, you will be very much like the men of Zebulun were in their loyalty toward David.

Check your heart. Is it inspired by the beauty, heroism, and love of the Messiah? If not, you just don’t know him well enough.

David is called a “man after God’s own heart.” Considering that he lusted after his neighbor’s wife, committed adultery with her, and had her husband murdered, the Lord’s description of him is remarkable. How could a man who was convicted a murderer and an adulterer also be called one after God’s own heart?

This passage in Isaiah contains a poetic play on words which is lost to any reader but one who understands Hebrew. A word for word translation runs something like this: “If not you will believe (lo ta-aminoo), surely not you will be established (lo te-amenoo).” The three letter Hebrew root – “aleph”- “mem”- “nun”, is the same in both words, and the Holy Spirit through the prophet Isaiah is clearly playing on this root to emphasize His point. The same root letters are also used in the spelling for the familiar word “Amen” which literally means “truthfully”.

“Break up your fallow ground.” In this context, the Lord is referring to breaking up the ground overrun with weeds and thorns creating a hardness to produce righteous fruit.

Momentum is simply the force or speed of movement that carries an object to its final destination. If you want to break through, you need to have a certain amount of momentum. In order for a rocket to blast into space, it needs tremendous momentum to break the gravitational barrier – but with the enormous power of jet engines and rocket fuel the ship is propelled faster and faster till it breaks free of the earth’s gravitational pull.

When the Apostle Paul wrote this letter to the Corinthians, he was speaking to a church that was surrounded with sexual immorality. The city of Corinth was a haven of hedonism where many temples hosted hundreds of prostitutes which were visited by vast multitudes of foreigners. In the ancient world, the term “Corinthianize” indicated a life of sexual promiscuity.

You know how sometimes we get a phone call from someone who didn’t intend to dial us? And what do we usually say? Sorry, you have the wrong number.

Judges 6 begins with an angel talking to Gideon saying, “thou mighty man of valor!” However, in this passage Gideon isn’t feeling very valiant — he’s consumed with his circumstances — how poor his family is and how he’s the least of his fathers’ house. He doesn’t feel he’s done anything worthy of being called valiant, yet the angel still addresses him “mighty man of valor!”
