“Go and shout this message to Jerusalem. This is what the LORD says: “I remember how eager you were to please me as a young bride long ago, how you loved me and followed me even through the barren wilderness. (Je 2:2 NLTse)
Even when our hearts grow cold toward God and our devotion to Him weakens, His love remains steadfast. We may forget God, but He remembers us.
God was concerned because the people of Judah had allowed their hearts to drift far from Him. …God reminded them of the love they had once had for Him, so that the memory might rekindle feelings of devotion and their hearts might return to Him.
If you do not guard your heart, you will grow cold in your love for Christ…You may not realize how far you have drifted from God until you contrast the love you are expressing to Him now with that of earlier days.
God has not changed. He is the same Person you gave your heart to when you became a Christian …
 “I am the LORD, and I do not change. That is why you descendants of Jacob are not already destroyed.  Ever since the days of your ancestors, you have scorned my decrees and failed to obey them. Now return to me, and I will return to you,” says the LORD of Heaven’s Armies.
“But you ask, ‘How can we return when we have never gone away?’ (Mal 3:6-7 NLTse)
