Unfortunately, during these terrible times when God's Word is most needed to help the people come to repentance, it will be almost impossible to find. When the people finally realize that God wants them to repent, it will be too late. The seeds of their destruction have been sown, and the crop is already ripe. The only truth available to them in the tumult of God's judgment is what they can remember. It is for this reason that God warns us in these times to "[redeem] the time, because the days are evil" (Ephesians 5:16).
If our hope in the Kingdom of God, the resurrection of the dead, and sharing life with God eternally are not sufficient to motivate us to repent, perhaps fear of a terrible calamity, the Great Tribulation, the Day of the Lord, or being spewed from God's mouth as a Laodicean will move us to use the present to secure the future. God prophesies to motivate us to cling to Him and His Word right now, and He is willing to scare us nearly to death in order to save us.
During this famine, "They shall wander from sea to sea, and from north to east; they shall run to and fro, seeking the word of the Lord, but shall not find it" (Amos 8:12). Amos probably refers to the Dead and Mediterranean Seas, east to west, and adds "north to east," describing a triangle with the south direction left out. Why would he do this?
On a map of Palestine, the Dead Sea lies to the east, the Mediterranean to the west and the nation of Israel to the north. What lies to the south? Jerusalem, where the truth was! In Amos' day, the truth was taught in God's Temple in Jerusalem.
Israelites wanted to be known as seekers of the truth, but in reality they did not want it. Their pride would not allow them to pilgrimage to Jerusalem for the truth, for that meant they would need to humble themselves before the Word of God.
Wander can be rendered "stagger" like a drunk or "tremble" like lips quivering in agitation because one is so angry or fearful he is unable to speak. It shows the people in a state of panic and intense agitation. They are desperately searching for what they had regarded so lightly: God, the Bible, His truth. But they cannot find them anywhere!
Thus they will seek any kind of religion, and many will fall prey to false ones. This scenario is already happening in modern Israel. New Age, mystical, and Eastern religions are growing steadily, and many "Christians" feel free to borrow "truth" from other religions. Additionally, recent years have seen the rise of ecumenical movements within a broad spectrum of religious bodies.
