You cannot be an good swimming teacher if you are not a proficient swimmer. And you cannot be an good driving instructor if you are not an experienced driver. Similarly, you won't be an effective evangelizer if you do not know the Lord well yourself. To know the Lord thoroughly is to surrender yourself to himself completely so that you may feel the zeal and inner fire and speak with passion and conviction. Otherwise, your message will only sound academic, dry, not-coming-from-the-heart, and lack power. To uplift others, let the Lord uplift you first. To inspire others, let him inspire you first. We should not spend so much time feeling sorry about how we fall short of loving God and trying to figure out how you should love him more. Instead, we should spend a lot more time focusing upon God's love and mercy, such great hope he has given us, and that he can actually help us overcome our sins and transform us into saints! The Holy Spirit does not like us to remain lukewarm; he wants to set our hearts on fire! Not letting ourselves go in God is stifling his Spirit.
