It's common to occasionally go to church or tell people you have one (that you don't really attend), but the question is have you made a defining step of receiving the forgiveness of Jesus and letting Him become the Lord over every area of your life?
You won't do this perfectly at any time you're on this earth, which is why His grace is so amazing... but you can do it relationally and intentionally. Again, don't presume you've really eaten, until you've really eaten. And then - don't miss out on the chance to "eat" with others at every opportunity.
"Taste and see that the LORD is good; blessed is the man who takes refuge in him." (Psalm 34:8)
"In the same way that the fully alive Father sent me here and I live because of him, so the one who makes a meal of me lives because of me. This is the Bread from heaven. Your ancestors ate bread and later died. Whoever eats this Bread will live always." (John 6:57-58, The Message)
"Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another —and all the more as you see the Day approaching." (Hebrews 10:25)
