In a work environment there are two phrases that come to my mind, "It's not what you know, it's who you know" and "It's not what you know, it's what you do with what you know, that makes a difference". You may know the meanings of these phrases in a work context. The first being ii doesn't matter how good you are at a particular role, if you want to get promoted or do well in a company you need to get to know some really 'powerful' people. The second phrase and slightly clumsily written, is about you know and what you do with it, effectively if you only learnt a few things and did something with all of that learning you would get by. I'm not sure where your opinion is on these, but each as they say in the place of work has benefits and risks!
Then there is Faith, recently the church I attend went to an event called Freelife. Marc Dupont a speaker at this conference, held at the Emmanuel Church in Durham, said a really important phrase to me, but in a different context with a completely different meaning, "It's not what you know, it's who you know" and that made so much sense to me. It's about the relationship we have, the relationship we have with Jesus to grow as individuals, church and followers of Him. That said, knowledge of God's word is important, because that is how we understand our God. So we could be challenged by "It's not what you know, it's what you do with what you know, that makes a difference". Ephesians 4:13 until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.
