This is essential for the Christian; you must have your personal time alone with Him. You put your life in peril if you do not. Church fellowship is essential and we need to be experiencing that to grow in the Lord. Worshipping in the family at home must also be there in our schedules. But we must not neglect being in the secret place with the Lord.
You have to find out what works for you. You may be able to operate on a spontaneous basis, whereby in the natural flow of life you are having space to worship the Lord and be with Him. However, for most of us, I suggest, that this is not the case, We need to be more disciplined. we need to set aside a specific time to be alone with our Father and our Lord Jesus. Regular habits are normally good in this respect.
And if your Quiet Time or personal time with the Lord is becoming dull and lacklustre then mix it up. Try whatever works. Try reading a few passages of good Christ centred books. The Puritans are good here and Richard Sibbes is always a good place to start. Try prayer lists. In all this make sure that your prayings and worshippings are Bible framed so you must have the Word.
Living Christians are always God’s presence Christians. No time in the presence of the Lord means death to your soul and impoverishment in spiritual desires and worship.
And of course our Lord Jesus sets the pattern here. He was so keen to spend time with his Father that he would get up early to make sure it happened. Perhaps that is what you need to do (and me). You need to be thinking about getting up a bit earlier and having time in His presence.
I have written about personal devotions at further length here if you are interested.
