7 Thus He showed me: Behold, the Lord stood on a wall made with a plumb line, with a plumb line in His hand. 8 And the Lord said to me, “Amos, what do you see?” And I said, “A plumb line.” Then the Lord said: “Behold, I am setting a plumb line in the midst of My people Israel; I will not pass by them anymore.” (Amos 7:7–8, NKJV)
Amos’ message was far from positive. God’s prophet had a dreadful message of punishment for the northern kingdom of Israel. Instead of standing upright against idolatry, immorality and injustice, they had participated in them. God’s plumb line, His truth, was in the midst of Israel, and they were not straight. God had repeatedly called them to repentance, but they would not return to Him. It was time to meet God (Amos 4:12). God’s word remains the standard of morality, teaching and faith. Everyone is judged by it (John 12:48-50; Romans 2:16; Revelation 20:12). God is longsuffering toward sinners, calling them through the gospel to repent (2 Peter 3:9; Romans 2:4). But, God is also just. His day of wrath will come, and we dare not have an impenitent heart toward His judgment (Romans 2:2-5). Like Israel, the church today is under threat of compromise with sin. Many have already accepted the world’s values and practices. The house of God will not escape judgment when we fail to stand upright and be faithful to the word of God (1 Peter 4:17-18). God’s plumb line is in the midst of His people (Galatians 1:6-10; 2 John 9).
