Hosea 10:2 Their heart is divided; now shall they be found faulty: he shall break down their altars, he shall spoil their images.

This passage is generally taken to be referring to the people of Israel. They had built altars to other gods, false gods, and some had taken to themselves graven images: Little good luck idols, if you will. But I believe it is applicable to the modern church and even to the individual person as a warning of the danger of a divided heart.
This Scripture tells us if the heart is divided then the condition of the life is faulty.

Jesus taught and said in Matthew 6:24, No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.

James 1:8 says, A double minded man is unstable in all his ways.

And again Jesus taught that a house divided against itself cannot stand.
Satan would like for us to cherish our bickerings until they become animosities and nurse those animosities into hatred.

To Bicker: To dispute.
Animosity: Ill will or enmity.
Enmity: Hostility.
Hatred: Intense dislike.

The smallest church in the world has potential for great good when it is of one heart and one soul.
But the largest, most wealthy, most gifted church in the world loses it's power and effectiveness the moment they become divided among themselves.
We are undone when the link of love is snapped.
The rule of division applies not only to groups or nations but to the individual to the heart of man.

Hosea 10:2 Their heart is divided; now shall they be found faulty.

We heard a woman say once, "I don't let my Christian life interfere with my social life."
Friend, if you get saved your Christian life will interfere with your social life. If it doesn't something is wrong.

Let's look at where the division strikes. It strikes at the heart, the vital region. Afflict my hand and you might slow me down, but afflict the heart and you affect the whole man.
The condition in our text is a serious one. It is not a heart that is weak and may be strengthened or palpitates at times. It is not a shallow beating heart, but one that is cleft in two. One organ that has become 2. I am speaking in a very natural fashion, but I am hoping you can see the spiritual side of what I am saying.

A divided heart is a deadly condition. A product of a divided heart is most often unhappiness and unsatisfaction. Who can be happy when their is a constant rival within himself.

Elijah told some people one day in I Kings 18:21, How long halt ye between two opinions? if the LORD be God, follow him: but if Baal, then follow him.

A person who has a divided heart has an internal battle going on all the time.
Satan wants to divide your heart. He wants to divide you from your prayer life, divide you from Bible study, divide you from church, divide you from fellow Christians, because the easiest way to defeat an enemy is to divide him from the source of his supply.

When Elijah spoke to Israel that day, Israel had become a people with a divided heart. Because of that condition God could not bless them because they were transgressing His Word. Baal could not bless them because he was not real. So they were left for the devil to afflict.

Matthew 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Mt 7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
Mt 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Ask yourself this question: "Whatever I have divided my heart with, whatever I have allowed to divide me from prayer, Bible study, Church, and the work of the church, how will it show up in the light of that day?"
Riches, success, worldly pleasures, community standing, worldly friends, etc, how will their worth be in the moment of death, the morning of the resurrection, the day of judgment?

Listen to me today. You cannot have an altar for God and an altar for the world (Baal) in the same house (heart). A house divided will not stand. You cannot love God and serve the devil too. You cannot take from each and give your heart to neither.
Elijah called on the people for a decision.

Hosea in our opening text prophesied the destruction coming to the faulty of heart.
There is a remedy. There is a cure, but first we must recognize our condition.

David prayed this pray in Psalm 51.
Psalm 51:2 Wash me thoroughly from mine iniquity, and cleanse me from my sin.
Ps 51:3 For I acknowledge my transgressions: and my sin is ever before me.
Ps 51:10 Create in me a clean heart, O God; and renew a right spirit within me.
Ps 51:11 Cast me not away from thy presence; and take not thy holy spirit from me.
Ps 51:12 Restore unto me the joy of thy salvation; and uphold me with thy free spirit

Repentance is not a promise. It is an act, a work, a turning away from.
The decision is yours. Eternity is in the balance.
