Mt 22:37-38, Mk 12:39-30, Mt 10:37-39, 1 Cor 16:22

We must love God. (Deut 6:5, Matt 22:37-38, Mark 12:29-30)

Deut 6:5 And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.

Matt 22:37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. 38 This is the first and great commandment.

Mark 12:29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: 30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.

We must love Christ. (Matthew 10:37-39, 1 Corinthians 16:22)

Matthew 10:37 He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me. 38 And he that taketh not his cross, and followeth after me, is not worthy of me. 39 He that findeth his life shall lose it: and he that loseth his life for my sake shall find it.

1 Corinthians 16:22 If any man love not the Lord Jesus Christ, let him be Anathema Maranatha.
