Matthew 22:34 But when the Pharisees heard that he had silenced the Sadducees, they gathered together. 35 And one of them, a lawyer, asked him a question to test him. 36 "Teacher, which is the great commandment in the Law?" 37 And he said to him, "You shall love the Lord your God with all your heart and with all your soul and with all your mind. 38 This is the great and first commandment. 39 And a second is like it: You shall love your neighbor as yourself. 40 On these two commandments depend all the Law and the Prophets."
When people ask us questions to prove us wrong, we need to follow Jesus' example and answer from the scriptures. The greatest commandment comes from Deuteronomy 6:5 and the second greatest commandment like it is found in Leviticus 19:18. How can we be able to answer critics from the scriptures?
We need to be systematically reading through the Bible daily year after year expecting the Holy Spirit to teach us (John 14:26a; 16:13). We have the capacity to understand the scriptures. Paul instructs us in 1 Corinthians 2:12, "Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God." We also need to depend on the Holy Spirit to help us remember the scripture passages we need to answer our critics (John 14:26b)
How do we love? We love because He first loved us (1 John 4:19) and gave us the capacity to love when we repented of our sin and believed the gospel (Ephesians 1:13-14; Galatians 5:22). We express love to God and man by obeying His commands by faith in the Son of God (1 John 5:2-3; Galatians 2:20). Love as a feeling ebbs and flows, but love can remain steady, even as feelings fluctuate, as we obey the Lord's commands. All benefit when we live a life of love. Think about this: Did Jesus command us to live a life of love and teach disciples to live a life of love in Matthew 28:19-20?
