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.

Here we have a stark word. Here we see the Lord testing Israel: “He gave you manna to eat in the wilderness, something your ancestors had never known, to humble and test you so that in the end it might go well with you.” [Deuteronomy 8:16]. Yet Paul says that they put Him to the test. A great irony occurs when God is testing us, and we despise His discipline, thereby testing Him.

Paul exhorts the church at Corinth about grumbling and complaining. He reminds the believers of the judgments that befell the 10 spies who brought a bad report of the land – and were struck down by a plague, and terrible fate of Korah and those aligned with him that came against Moses and Aaron and were swallowed up by the ground under them.

For the past two weeks we’ve been building life lessons derived from the Exodus wanderings and from Paul’s exhortations to the church in Corinth. Notice carefully that Paul says, “these were written for our admonition upon whom the ends of the ages have come”…

…that is, written for us today! – admonitions from Paul to learn lessons from the history of the children of Israel.

For the past two weeks we have examined lessons from the OT account of Israel’s Exodus from Egypt in hope of avoiding the errors and attitudes of the children of Israel. This week we will draw connections between the Exodus and the prophecies in the book of Revelation.

Over the past few weeks, we’ve begun a series of devotions based on the Exodus wanderings of the Children of Israel, and their tragic mistakes which we can learn from and avoid. One powerful influence common to their failures was fear.

The Lord spoke to Moses, who led the children of Israel out of Egypt to be desperately cornered with the Red sea before them and Pharaoh’s chariots advancing upon them from behind. Overwhelmed with terror they cry out to Moses, “It would have been better for us to serve the Egyptians than to die in the desert!” Having just miraculously escaped from the miserable life of slavery, and only beginning their new life of freedom, the children of Israel were faced with the most dire threat to their existence.

When Peter and John had gone up to the Temple for prayer [Acts 3], they saw a man who was lame from birth, and were moved to heal him in the name of Yeshua (Jesus). Immediately the religious leaders laid hands on them [Acts 4:3] and kept them imprisoned for a day. The following day, with boldness, they declared this miracle was done in the name of Yeshua. I love what the “religious” leaders said next — “they perceived that they were unlearned men and they marveled at their boldness!” Why were they bold? They had been with Yeshua, and the leaders took note of that!
