Love the LORD thy God with all thine Heart, and with all thy Soul

• Love God with all our heart, all our soul and in all our strength is the first greatest commandment

Deu 6:4-6 “Hear, O Israel: The LORD our God is one LORD: And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might. And these words, which I command thee this day, shall be in thine heart…”

Matt 22:36-38 "Master, which is the great commandment in the law? 37Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. 38This is the first and great commandment. " 

• More than all whole burnt offerings and sacrifices and Jesus fulfilled this commandment by keeping his Father’s commandment and offering up himself

Mark 12:33 "And to love him with all the heart, and with all the understanding, and with all the soul, and with all the strength, and to love his neighbour as himself, is more than all whole burnt offerings and sacrifices."

Heb 10:8-10 “Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. By the which will we are sanctified through the offering of the body of Jesus Christ once for all.”

John 10: 17-18 “Therefore doth my Father love me, because I lay down my life, that I might take it again. 18No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.”

• Matter of heart. God looks at the heart

Isa 29:13 “Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men.”

1 Sam 16:7b “... for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart.”

Pro 21:2 “Every way of a man is right in his own eyes: but the LORD pondereth the hearts.”

Mat 12:34b "... for out of the abundance of the heart the mouth speaketh.”

Psa 19:14 “Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer.”

• Man’s heart is sinful and desperately wicked 

Jer 17:9-10 “The heart is deceitful above all things, and desperately wicked: who can know it? I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.”

Gen 6:5 “And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.”

• Circumcision of heart “by God” [must be born again from above] is required to love our God with all our heart

Rom 2:29 “But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.”

Deu 30:6 “And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.”

Ezekiel 36:26-27 "A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. 27And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them."

• Circumcision of heart achieved by the two edged sword, which is Bible

Heb 4:12 “For the word of God is quick [alive], and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.”

Acts 2:37 “Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?”

Rom 10:17 “So then faith cometh by hearing, and hearing by the word of God.”

• Loving God is keeping God’s commandments. Obedience is the evidence of Love.

John 14:15 "If ye love me, keep my commandments."

1 John 3:18 "My little children, let us not love in word, neither in tongue; but in deed and in truth."

1 John 5:3 "For this is the love of God, that we keep his commandments: and his commandments are not grievous."  

John 14:21 "He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him."
