If a person claims to Love and know God, but it is clear in their actions that they are not loving/Loving towards the people around them, then this means that they actually do not know God. God is the epitome of Love and we cannot have a relationship with Him if we do not express Who He really is.
And we pray:
Dear God, I pray that I may never be ignorant of the way I treat people. Lord I want to know You completely and I know that in order for me to do that, I need to be loving/Loving to every single person around me. May You help me live this out, Lord. In Jesus’ name, I pray. Amen.
So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking. They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts. Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, with a continual lust for more. You, however, did not come to know Christ that way. Surely you heard of him and were taught in him in accordance with the truth that is in Jesus. You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness. Ephesians 4:17-24
