One is that the value of all things hinges on setting creation's relationship with God right. Since God did all the restoring work in Jesus Christ, we have more than enough to be thankful for. If the work of restoration was done by Jesus, then for anything we do to be meaningful, it must go to and through Him. Thus, the Holy Spirit's work today can be found by how it leads people to the Spirit's sender, Jesus. Whatever miracles, signs, wonders and manifestations the Spirit does are done to glorify Christ, and have their value in how they help make the community which spreads Christ's good news stronger and truer.
Miracles can and do happen.
Always have and always will, in places where the Church is on the advance. Gifts of all kinds are still being given, and will be until the Kingdom comes and the task is complete. God has neither gone deaf nor fallen silent. Indeed, at times God chooses to shout over the clatter, so that the deaf of mind have no excuses. There are some other things to bear in mind as you explore matters of the faith, here and anywhere else.
