My Dear Child,
Among the great and interesting things of nature are the trees. Some grow slowly and others grow very fast, such as the eucalyptus, which can grow 10 meters in a year and can reach more than 60 meters in height. They are very useful to our health as well.
As you grow and do good before God, you will be just like the eucalyptus tree, strong and great and everything will work out for you. Psalm 1:1-3
With love, Dad/Mom
