Reading daily.

2 Timothy 4v3-5
For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths. As for you, always be sober-minded, endure suffering, do the work of an evangelist, fulfill your ministry.

It is important for us to stay in the word daily and feed ourselves. Of course looking to others such as ministers and church leaders is a great tool for growth and maturity in our spiritual lives but we must read for ourselves the word that comes from God to know it deeply as to not be led astray. And reading by the Spirit looking for truth that supports Christ and his sacrifice not what our itching ears want to hear avoiding wandering and falling from the truth.
