No all Christian converts can join a church - most Christian churches are not worth joining and most are not Christian but anti. Among those who do join a church not all can be active or devout. Not all real Christian churches provide an all-round experience - some are dry, cold, black and white; others are excessively communal for some people - others are not communal enough.
In sum: everybody should be a Christian, but not everybody (here and now) can or should join a church.
So what then? How on earth can the Christian convert (or the cradle Christian, for that matter) get support, be encouraged, experience relatedness, joy, connection when there is no church - or no church that provides this kind of thing?
How, in sum, can a Christian convert experience that which many crave - the re-enchantment of everyday life - when they are pretty much 'on their own'?
I can only offer a shopping list of suggestions. In no particular order.
1. As a general attitude: approach your religious life as a process of trial and error - make trials, expect to make errors; repent, learn, try again.
2. Meditation - various methods. Much depends on the purpose - if aiming to get power: bad; if aiming for joy and cheer then it depends on how; if aiming for communion with God, to understand, to feel divinity - then Good.
3. Prayer - very varied. From short repetitions or short spontaneous prayers (thanks, requests etc) to long formal prayers, written prayers, improvised/ inspired prayers. All Christians will pray to the Father in the name of Jesus - some Christians add others.
4. Read scripture. Some people are systematic (from the start to the end), others have a plan (for example the evangelical plan or reading the Bible by LAGER: Luke, Acts, Genesis, Exodus, Revelations); others just read what they feel drawn to read - some read in small intensely considered passages; others take in a large sweep of text to get a 'feel' for things.
5. Focus on the work of specific persons, and the people who are recommended by them or who have been influenced by them. E.g. CS Lewis, Father Seraphim Rose, Terryl Givens.
6. Attend churches sometimes for specific reasons (rather than 'joining' a particular one) e.g. for the joyous liturgy, the teaching sermons, the music, the people.
7. Read inspiring devotional Literature/ Poetry/ Essays - Herbert's poetry, Pascal's Pensees, Traherne's 'Centuries of Mediations' that kind of thing.
Then reverse the prescription of Robert Burton and Samuel Johon who tried to avoid melancholy and: Be Solitary, Be Idle (unstructured time). Feel life happening.
Seek quite, rural, peaceful journeys, mornings and evenings - or night.
Either try for multiple daily spiritual injections of the above - or else a period of some days of total immersion in the above (a retreat).
