Our love for God

Teacher, which is the greatest commandment in the Law?"Jesus replied: " 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment. And the second is like it: 'Love your neighbor as yourself.' All the Law and the Prophets hang on these two commandments.
Matthew 22:36-40

"If you love me, you will obey what I command. And I will ask the Father, and he will give you another Counselor to be with you forever— the Spirit of truth. 
1 John 14:15-17

Be imitators of God, therefore, as dearly loved children and live a life of love, just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God. 
Ephesians 5:1-2
