What does the Bible say about seeking God with all your heart?

In Jeremiah 29:12-13, God promises that those who call upon Him and seek Him with all their heart will find Him. This passage reflects the importance of earnest prayer and sincere seeking of God, especially during difficult times. The historical context shows that Israel was in captivity, and despite their dire circumstances, they were encouraged to reach out to God. This is a timeless truth for all Christians, as it reaffirms that God is always accessible to those who genuinely desire to know Him and walk in His ways.
