My third reason relates to the age of your peers. Humanly speaking young people are much more likely to respond to the gospel than people who are older. Of course, God can convert anyone, and He has, and He will. There have been some spectacular conversions of middle-aged and elderly people. But generally speaking, the longer a person has persevered in unbelief the harder they are to change.
Young people are more adaptable, more open to considering new ideas, more responsive to the gospel.
You are living in a time of life when your friends are at their most receptive to the message about the Lord Jesus. We live in changing, yet exciting times. These are days full of challenge and opportunity. You, as young people in the Reformed Churches, are well placed in doctrine and background to make good rise to the challenge and to use the opportunity.
