“Paul calls the church to think and act with greater maturity. He argues that the key issue is not merely legitimacy but spiritual profitability.
The question we need to be asking is not:
‘Is it alright for me to do this as a Christian?’
But rather these questions:
‘Is this going to build up?’
‘Is this going to strengthen the fellowship of God’s people?’
‘Is this going to advance my goal of running towards Jesus Christ and glory?’
‘Is this something that laying to one side will better enable me to serve Christ?’
So mature Christians develop an instinct to ask:
‘Will this bring most glory to God?’
‘Is this wise?'”
