Signs of the times
In Old Testament days, God would withdraw His loving care and protection from Israel when the people rejected His truths and "walked in the counsels and in the imagination of their evil heart." (Jeremiah 7:24) Left to their own resources, they often faced plagues ("serious and prolonged sicknesses"), drought, famine and wars -- sometimes locusts -- all of which would increase in end times.

"...when you have eaten and are full, and have built beautiful houses and dwell in them... your heart is lifted up and you forget the Lord your God. ... you say in your heart, ‘My power and the might of my hand have gained me this wealth.’
"...if you by any means forget the Lord your God, and follow other gods... you shall surely perish. As the nations which the Lord destroys before you, so you shall perish, because you would not be obedient to the voice of the Lord your God."
Deuteronomy 8:10-20
Read 1 Corinthians 10:1-13 and see how this prophecy, given to the nation Israel, applies also to other nations blessed by God. Then read Preparing for Victory and delight in His protection for those who love and follow Jesus.
