As a Christian father, you must remain alert as long as your children are under your authority. Even after they leave the home, you may still be able to, and should, exert regular positive influence, even with your grandchildren (Deuteronomy 4:9).
As for you single’s, you are training for that duty right now by 1. learning to pay attention to others, 2. by learning how to treat women and children with honor, 3. by dating honorably and learning to be attentive to the needs of single ladies, 4. by striving to serve the widows (elders) and the fatherless (elders). These responsibilities also remain after you marry. Remember open your eyes by anointing them.
In your conversations, look for needs. Ask about things you can help with or you can find someone else to help with. Find things you can pray about. Pay attention!
Here is a specific example of masculine leadership that arises regularly in a family: telling your children what to do. An engaged Christian father regularly issues instructions as he actively directs his children to do things that will benefit them and others. But it only starts there.
Once you tell your child to do something, you must then pay attention to the child’s attitude toward that instruction, and then to his or her performance. You cannot simply give an instruction, return to what you were doing and forget what you said. Children, particularly if untrained, will often test the limits of your authority. If you give some direction and then return your full attention to what you were doing before, you are training your child not to be overly concerned about your commands. The child you just told to stop racing his car on the coffee table will go right back to it.
Once you give a command, remain on duty. Ensure the child follows through. This must be the case at home, in public, at Church services, everywhere. You simply cannot expect good results if you lose track of what you have instructed your child to do and fail to make sure the lesson sticks.
The duties of a man are constant. They require vigilance. They require you to work the works of Him that sent you, while you can. Be urgent. Recognize the onrushing river of opportunities for what it is. Seize each one and let God’s influence come into other people’s lives through you. Express dynamic male leadership. Put Godly manhood into action!
God can do so much in your life through your manly role. He can make your home life enriching and wonderful. He can grant you a promotion at work. He can add purpose, spark, and joy to the lives of the people around you. He can cause your girlfriend or wife to blossom emotionally, intellectually, spiritually. He can nourish your children or grandchildren into joyful, wise, and enjoyable young people. He can make you a different man, your family a different family, and your work a different work!
But you must anoint your eyes. See where God wants to lead you, what He wants to make of you, and how He wants to bless others through you!
