Mark:12: [28] One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, “Of all the commandments, which is the most important?” [29] “The most important one,” answered Jesus, “is this: 'Hear, O Israel, the Lord our God, the Lord is one. [30] Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.' [31] The second is this: 'Love your neighbor as yourself.' There is no commandment greater than these.”

Dueteronomy:6: [4] Hear, O Israel: The LORD our God, the LORD is one. [5] Love the LORD your God with all your heart and with all your soul and with all your strength.

Leviticus:19:18: “... but love your neighbor as yourself. I am the Lord.”

01. OBEY THE LORD WITH ALL YOUR HEART AND SOUL:

Dueteronomy: 26:16: The LORD your God commands you this day to follow these decrees and laws; carefully observe them with all your heart and with all your soul.

Psalm:119: [33] Teach me, O LORD, to follow your decrees; then I will keep them to the end. [34] Give me understanding, and I will keep your law and obey it with all my heart. [35] Direct me in the path of your commands, for there I find delight.

02. SERVE THE LORD WITH ALL YOUR HEART AND SOUL:

Deuteronomy:10: [12] And now, O Israel, what does the LORD your God ask of you but to fear the LORD your God, to walk in all his ways, to love him, to serve the LORD your God with all your heart and with all your soul, [13] and to observe the LORD's commands and decrees that I am giving you today for your own good?

Dueteronomy:11: [13] So if you faithfully obey the commands I am giving you today-to love the LORD your God and to serve him with all your heart and with all your soul- [14] then I will send rain on your land in its season, both autumn and spring rains, so that you may gather in your grain, new wine and oil.

Joshuah:22: [5] “But be very careful to keep the commandment and the law that Moses the servant of the LORD gave you: to love the LORD your God, to walk in all his ways, to obey his commands, to hold fast to him and to serve him with all your heart and all your soul.”

1 Samuel:12:20: “Do not be afraid,” Samuel replied. “You have done all this evil; yet do not turn away from the LORD, but serve the LORD with all your heart.”

1 Samuel: 12:24: But be sure to fear the LORD and serve him faithfully with all your heart; consider what great things he has done for you.

03. SEEK THE LORD WITH ALL YOUR HEART:

Jeremiah:29: [12] “Then you will call upon me and come and pray to me, and I will listen to you. [13] You will seek me and find me when you seek me with all your heart. [14] I will be found by you,” declares the LORD, “and will bring you back from captivity.”

Psalm:119:9: How can a young man keep his way pure? By living according to your word. [10] I seek you with all my heart; do not let me stray from your commands. [11] I have hidden your word in my heart that I might not sin against you.

Psalm:119: [57] You are my portion, O LORD; I have promised to obey your words. [58]I have sought your face with all my heart; be gracious to me according to your promise. [59] I have considered my ways and have turned my steps to your statutes.

Psalm:119: [145] I call with all my heart; answer me, O LORD, and I will obey your decrees. [146] I call out to you; save me and I will keep your statutes.

04. REPENT WITH ALL YOUR HEART AND SOUL:

Joel:2: [12] “Even now,” declares the LORD, “return to me with all your heart, with fasting and weeping and mourning.” [13] Rend your heart and not your garments. Return to the LORD your God, for he is gracious and compassionate, slow to anger and abounding in love, and he relents from sending calamity.

Dueteronomy:30: [4] Even if you have been banished to the most distant land under the heavens, from there the LORD your God will gather you and bring you back. [5] He will bring you to the land that belonged to your fathers, and you will take possession of it. He will make you more prosperous and numerous than your fathers. [6] The LORD your God will circumcise your hearts and the hearts of your descendants, so that you may love him with all your heart and with all your soul, and live. [7] The LORD your God will put all these curses on your enemies who hate and persecute you. [8] You will again obey the LORD and follow all his commands I am giving you today. [9] Then the LORD your God will make you most prosperous in all the work of your hands and in the fruit of your womb, the young of your livestock and the crops of your land. The LORD will again delight in you and make you prosperous, just as he delighted in your fathers, [10] if you obey the LORD your God and keep his commands and decrees that are written in this Book of the Law and turn to the LORD your God with all your heart and with all your soul.

05. TRUST THE LORD WITH ALL YOUR HEART:

Proverbs:3:[5] Trust in the LORD with all your heart and lean not on your own understanding; [6] in all your ways acknowledge him, and he will make your paths straight.

06. PRAISE THE LORD WITH ALL YOUR HEART:

Psalm:9: [1 I] will praise you, O LORD, with all my heart; I will tell of all your wonders.
[2I] will be glad and rejoice in you; I will sing praise to your name, O Most High.

Psalm:138: [1] I will praise you, O LORD, with all my heart; before the “gods” I will sing your praise. [2] I will bow down toward your holy temple and will praise your name for your love and your faithfulness, for you have exalted above all things your name and your word.

07. REJOICE WITH ALL YOUR HEART:

Zepaniah:3: [14] Sing, O Daughter of Zion; shout aloud, O Israel! Be glad and rejoice with all your heart, O Daughter of Jerusalem! [15] The LORD has taken away your punishment, he has turned back your enemy. The LORD, the King of Israel, is with you; never again will you fear any harm.

08. KNOWING WITH ALL YOUR HEART AND SOUL:

Joshuah:23:14: “Now I am about to go the way of all the earth. You know with all your heart and soul that not one of all the good promises the LORD your God gave you has failed. Every promise has been fulfilled; not one has failed.”
