Wonderful to have the ability Simon/Melody to write your thoughts like this - ahead of parenthood! I guarantee you WON'T have time for it and parenting - and studying and being that special hubby/wife to each other! It just won't happen! So, as 'an elderstatesman' as you put it, here is some advice:
1. Take time NOW to enjoy that wife/husband afresh - yes, every day, with every groan and every sigh - enjoy the time together NOW!
2. Take lots of time for the scriptures together and alone! You will have TO MAKE TIME later and the rest of that life of yours!
3. Enjoy the fact that a new life will be coming into your lives together - and make fresh promises to each other and to the Lord on behalf of this 'child' - Hannah like - for 'this child I prayed'!
Will write something more later,
