If you want to go deeper with God you have to pay the sacrifice, sacrifice of time, of praise, of worship. You say you don’t have time because of family responsibilities well what is actually important to you?

If it matters you’ll make time. Salvation comes for free but fire is costly… Seek God til that fire drops on you and you have fire on your tongue. Only then are you qualified to preach. God is a rewarder of all those who diligently seek Him. You can study in the seminary but until you have laboured in the Secret Place you will always lack power.

You may have reasoned arguments but your words will have no power to affect change. It’s the measure of the Spirit that you carry that matters with preaching and this doesn’t just fall on your lap you have to pay the sacrifice.
