Hey Brother,
I thank the Lord that you want to get involved..If you can't find a church to get involved in ..don't let that stop you..I also plan to labor for the Lord this summer..There is only 21 school days left..Here are some things a person can do without even belonging to a church.
A. Go to your local salvation army or other outreach to the poor and ask if you can be of any service..That will be my first stop..The Talbot House.
B. Go to your local nursing home .I play the guitar..you could ask if you can do a weekly Bible study ..give a short message and sing a few songs.
C. Your local jail.I used to be a volunteer chaplain..You simply fill out a little paper work..be available.Jesus will fill your mouth with the right words.
D. A sign ministry..I've stood out by a busy intersection before for about 1 1/2 years wearing a huge sandwich board.I'd changes Bible verses every month..I would paint my boards with 4 inch letters..Many would stop..I would also give out tracts..
E. Help an elderly neighbor with yard work..wash her car etc..
There is plenty to do..
F. Also ..there are some short term mision trips available with some organizations..can be found on line..
Churches are great ..but don't let a closed door keep ya from serving the Lord.
"The harvest is great by the laborers are few..pray ye that the Lord of the harvest would send laborers in the harvest."
