I thought that there was no point in running a full node without mining?
Since you're not verifying any transactions, there's almost no point to it other than propagating transactions to someone else who can provide the PoW needed for the next block.
you are confusing miners with nodes together. it is the complete opposite. a miner doesn't "verify" transactions since it is the nodes job to do that! a node receives transactions, checks their signature, size, rejects double spends and propagates them to the rest of the network if they are valid. then a miner who finds a block takes the already valid transactions and puts them in the block they found.
that is why nodes are the back bone of a decentralized currency like bitcoin.
