God has children and never grandchildren. Do not base your relationship with Him off of Chruhc membership , attendence, etc.
One question, are you born again?
A couple of comments- going to worship God can be a wonderful experience. Last night I went to a prayer/worship meeting. That was the 6th one they had in the last 8 days. Some were nice, some were powerful and one was flat awesome. Last night was dry as a bone in the dessert sun for me. Still others around me got touched. I decided to stay because I came to seek and honor God and I do not base that on how much I enjoy something. Besides every gathering is different and God may be meeting someone else's needs.
All that being said, lets go back to the first question. If the answer is yes then you must simply press into His presence. You have heard a lot about Him over the years but it is time for you to get to know Him personally.
Find a quiet place and worship for an hour or two. Spend time praying (talking to Him about everything). Learn His Word for it is a love letter to you. Press in, spend some time getting to know Him, He is worth it.
If the answer is no or I do not know then may I suggest praying this with an expectant heart:
Rom 3:23 For all have sinned, and come short of the glory of God;
Father I am truly sorry for my sin. Thank You for sending your Son to die on the cross for me. Thank You that He rose again and that this resurrection life can be mine through Jesus.
Act 15:11 But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
Rom 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Rom 10:10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Father I choose to believe that Jesus took my place on that cross. Jesus come into my heart, I confess You as my Lord and Savior.
Thank You that I will never be the same as I have received new life from You. Thank You that Your wonderful Holy Spirit is going to indwell my heart, lead me into all truth, reveal Your heart to me and teach me Your Word!
Father I receive these things and I thank You both for hearing and answering,
in Jesus Name I pray amen.
