From https://www.bible-studys.org/Bible%20Books/Amos/Amos%20Chapter%204.html:
“Verses 6-11: Past warnings were futile, a fact repeatedly emphasized by “Yet you have not returned to Me” (verses 6, 8-11).
Before confronting sinners in final judgment, God has often used drastic measures, in this case, famine (4:6), drought (4:7-8), the devastation of crops (4:9), plague (4:10, and warfare (4:10); in an effort to get people’s attention and bring them to repentance. Still, Israel would not return to Him. Every person must “prepare to meet … God”, either as loving father or as divine Judge (Heb. 10:31; Rev. 20:15).”
We love messages of God’s Mercy, and this, believe it or not, is a Great Mercy. Because God loves us, He warns us. We must turn back to Him or face the consequences…
For a list of some of God’s previous warnings, read Amos 4. Although this happened in the Old Testament, that does not mean it will not happen today.
While we can’t control what others choose, we can control what we choose.
“And as for me and my house-we will serve the Lord. I hope you to choose to do so too ?
