Well considering that your old church (from what you have written on this topic) isn't giving you anything and will eventually make you spiritually die, Yes it is time to find a new church. I dealt with the same thing a couple months ago 4 to be exact. My old church was spiritually dyeing and so was my family. Then a friend of my mom and me who went to the church we went to at that time and had left a month before us found a different church. Her family was growing spiritually. So we went to her church a couple times and God had called us there. Since then I got the Holy Ghost and so did my brother and my mom. In conclusion I think that leaving might be a pretty good decision if you feel that God is calling you to leave. I will definitely be praying for you God bless you and have a nice day.
