“[…] ‘You will search for me with all your heart. And I will let you find me,’ declares Jehovah.”
~Jeremiah 29:13,14

How do we show God we are sincerely searching for him?
One way is through heartfelt prayer.
“Make me know your ways, O Jehovah; Teach me your paths.” (Ps. 25:4)
Like the psalmist, we need to display humility and recognize we need God’s guidance.
Jehovah invites even those who have strayed from him to come back to him.
“If you search for Jehovah your God from there, you will certainly find him, if you inquire for him with all your heart and with all your soul. When you are in great distress and all these things have happened to you in later times, then you will return to Jehovah your God and listen to his voice. For Jehovah your God is a merciful God. He will not desert you […]” (De. 4:29-31)
But it is not enough to recognize our own sins. (La. 3:41,42)
Seeking Jehovah implies learning about his personality: what God likes and dislikes and then conforming to his standards. (Je. 31:34)
To find God, we must try to imitate his mercy, ridding ourselves of feelings of hatred toward those who have wronged us. (Mt. 6:12)
Then God allows us to find his peace and a solid hope for the future. (Jer. 29:11,12)
