March 4

It is often difficult for us to do things because they are so very different from what we are used to, not because the thing itself is particularly difficult. With you, and indeed most Bahá'ís, who are now, as adults, accepting this glorious Faith, no doubt some of the ordinances, like fasting and daily prayer, are hard to understand and obey at first. But we must always think that these things are given to all men for a thousand years to come. For Bahá'í children who see these things practiced in the home, they will be as natural and necessary a thing as going to church on Sunday was to the more pious generation of Christians. Bahá'u'lláh would not have given us these things if they would not greatly benefit us, and, like children who are sensible enough to realize their father is wise and does what is good for them, we must accept to obey these ordinances even though at first we may not see any need for them. As we obey them we will gradually come to see in ourselves the benefits they confer.
