1) Pray together with your wife, Go to Him in Thanksgiving for everything, pray over your child, your marriage, your home, over the people you and your wife and child come into contact with, tell the devil in Jesus's name, "This child is a child of God's you cannot have him."
2) Take your wife and child to church, find one together that is large enough to have a good children's ministry, a good selection of small groups for you and your wife, and one that the pastor speaks from the Bible.
3) You've heard it and read it on here, your child will be a sponge, read to him, let him see you read everyday from the Bible and from a leadership book, at least a few minutes everyday. Let him hear you quote scripture over certain events, both good and bad. LET HIM HEAR YOU PRAY AT NIGHT! This isn't just his little kids prayers, let him "catch you" saying some prayers. Let him hear you sing worship songs in the car, I promise this will be a lot better than you realize. Sometimes these songs will be adult Christian songs, sometimes sing with children's songs. Put them on Youtube at the house and dance and sing to them.
4) Let your child see you treat his mom with tender care!!!!!!!!!!!!!!! Let him see you hug his mom in tender embraces. Let him hear you speak to her, "words of life and not death." The power of the tongue is greater than a sword.
5) Take lots of pictures has been said, but can't be emphasized enough.
6) Teach him how to tithe and how to save and why both are important. Set up the mutual funds account, set it to the biggest and fastest growth you can, there is plenty of time for highs and lows. Buy an ounce or two of Gold every year for him, put it in a safe or box at a bank.
7) I learned this one with my grandchild, -------- set up an email account for them, then, type them something as things happen, write them an email telling them what all you did that day or week, (don't let it go longer than a week, you will forget the little things), tell them the little things, the great things, maybe a bad thing that happened (not just to them but maybe to you and/or mom), tell him your thoughts, end the email in a prayer, let him here your anguish over something you have done or didn't do, let him hear your praise to God, let him hear how you want him to be covered by God's heavenly armies and covered by the Holy Spirit and walk with him. Now you won't give him this email address and password until "it's time." Yeah, teenager, 20's, 30's, the wife gives it after you're gone, I can't tell you when to give it to him, you will know that one, dad! Leave the email and password in your will just in case.
8) You may live in this world, be not of this world. Teach him how to put on the full armour of God everyday.
