“Give to every one who asks you, and don’t ask for it back. The Father wants his blessings shared. Happy is the giver who lives according to this rule.”
Didache, a.k.a. The Teaching of the Twelve Apostles trans. and ed. by Tony Jones, 1.5.1.
The Didache is one of the earliest Christian documents, dated to the second half of the first century. It’s a must read as it reflects both the simplicity of the teachings of Jesus and represents the corpus the first disciples used to make disciples.
