Now may our God and Father Himself and Jesus our Lord direct our way to you; and may the Lord cause you to increase and abound in love for one another, and for all people, just as we also do for you; so that He may establish your hearts without blame in holiness before our God and Father at the coming of our Lord Jesus with all His saints. 1 Thessalonians 3:11-13 (NAS)
The only way we can come close to blamelessness on this earth is to be purified by love, for other Christians, and for all humankind. Only our love of the Lord gives us the ability to love others despite our tendency to hate them. Only he causes our love to increase. It is very hard if not impossible to be in the act of loving someone and be at fault. That’s how the Lord wants to find us when he comes for us.
