I've been reflecting on this since meeting with a bunch of good friends the other evening. We meet about once per month to discuss the Christian life and learn from each other. I'm the odd one out being well into my 50s with most of the other guys being late 20s! It's great to challenge each other and talk through personal struggles as a believer. One of them re-iterated just how hard he found it to settle down to a regular time with God. We suggested that like much else in life it could be helped by planning. So if it was intended to spend some time with God in the morning why not plan what part of the Bible to read the night before-indeed why not go to bed early enough the night before to make it happen! Someone quoted Rico Tice as saying that if someone saw him still up and about at 11pm that he had clearly planned not to spend time with God the next morning!
Thankfully the Christian gospel is based on grace and not performance, so we needn't beat ourselves up. But, as John Newton says in one of his 'letters to a nobleman', 'from the time we know the Lord, and are bound to Him by cords of love and gratitude, the two chief points we should have in view are, to maintain communion with him in our own souls, and to glorify him in the sight of men.'
The best short article I've read on this is by Tim Keller when he speak about prayer life that nourishes the soul. It's well worth a read.
