The interconnectedness of the worlds computers and smart phones is accelerating the increase of human knowledge at an exponential rate.
To find out if anything is of value to your progression in spiritual things, its worthiness can be found out by asking the Holy Spirit to guide you in evaluating it, whether it is true or false, and whether it is of God. The very rigorous evaluation of the hammers strike against the object on the anvil will quickly determine if the object rings true or disintegrates and falls away as dross (false or not of God ). The Holy Spirit is within you, waiting for your asking for Comfort and Guidance.
