There is a Great Need
in many churches today for leaders to give regular encouragement and equipping for parents on their family discipleship journeys. If you are here thinking about doing that for your congregation praise God! It's not a popular or easy topic to speak on, but it is one that many families need to hear about.
So, with your context in mind, consider the needs of your congregation in two areas:
Why?
They need a clear, motivating vision of why family discipleship is important. And they don't just need this as a one off. The challenges and temptations of daily life will lead us off course from our convictions regularly, so consider your congregation's need for ongoing encouragement in this area.
And please take to heart how counter cultural the call of God is on Christian parents. The voice of culture will be in the ears of your saints, in varying degrees, on the topic of parenting. May your church speak clearly and powerfully against this with God's wonderful plan for parenting.
How?
It is no good to tell someone how essential and powerful something is without telling them how to do it. There is no need to be one size fits all, but you can provide your congregation with training and resources that they can use in a way that fits their family context. There may be some who have not grown up with good examples of godly parenting and many of these concepts may be new and daunting to them, so prayerfully consider what practical help and support you can provide in setting them up for success.
