"But the Lord has strengthened Rezin's foes against them and has spurred their enemies on. Arameans from the east and Philistines from the west have devoured Israel with open mouth. Yet for all this, his anger is not turned away, his hand is still upraised." NIV translation
God has brought enemies victory over Israel and yet He is still angry with His people. We have been so focused on the fact that God is love that many believers do not even understand that God is also a jealous God. If it takes bringing enemies against you to get you back on track with Him, then that is what He will do.
"But the people have not returned to him who struck them, nor have they sought the Lord Almighty." NIV translation
The purpose of the judgment that was brought on God's people was to bring them to repentance. This is where our will is broken and our minds are brought into agreement with what God says is right.
This leads to a changing of direction from our path to His path. It was this way throughout the Old Testament and it is the same for us today. Does it seem like God is against you? If that is the case, then we need to examine our lives to see if this repentance has happened and we are indeed following God's will for our lives.
"So the Lord will cut off from Israel both head and tail, both palm branch and reed in a single day; the elders and prominent men are the head, the prophets who teach lies are the tail." NIV translation
The leaders of Israel had led the people of God in the wrong direction. Even after God's correction they did not tell the people to repent and turn to God. Therefore, God says that He will remove them from their positions. That same type of responsibility applies to Christian leaders today in that, if they are leading God's people astray, God will remove them from their office in due time.
It may be from a scandal which has happened many times recently or it could simply be God calling them home but either way they will be removed from their positions.
"Those who guide this people mislead them, and those who are guided are led astray." NIV translation
We see from this verse that not all of the blame is placed on the leaders. Those that follow them also receive blame and judgment. That is why it is important for us to read and study God's Word and let the Holy Spirit speak to our hearts because, in the end, we are all responsible for our own walk with the Lord.
