Hi, I would say that spirituality is a mindset of the soul, or a condition formed within the mind and the heart that believes, 1 John 5:1-4. Salvation itself will provide true and accurate spirituality because we become sons of God. If you believe in something really believe, we were told in the Bible that with true faith developed in us then nothing would be impossible for us to do, Matthew 17:20. In this world we form understanding about a condition or a situation before we can confirm authentic value, Romans 13:11-14. As regard God and the actual existence of him is hard to define since there is no physical form and this is viewed as the unknown so it blocks confirmation simply because we have no physical proof to see which will act as a confirmation factor, 2 Timothy 4:3-4.
But God has been wise enough to provide the Bible as the actual physical proof since God understands the minds of humans and what we need to progress towards finding true spirituality, John 17:17. The Bible predicted that in the final days' truth will be hard to acquire because the religious practices of "believers" have changed, 1 Timothy 4:1-2. Another point is that the prediction of the final days can cause us to question what we really believe and who is the one teaching us "Truth", 2 Timothy 3:14-17. All these things really help build or destroy spirituality so that finally when the Lord arrives at the Second Coming the Bible would have either failed or succeeded, Luke 8:9-15.
