Take care then how you hear, for to the one who has, more will be given, and from the one who has not, even what he thinks that he has will be taken away. (Luke 8:18,ESV)
What is it that we have? Knowledge? Power? Wealth? Wisdom? God often speaks to us of seeking and gaining wisdom and understanding. He never exhorts us to desire power or wealth. Rather, the more of wisdom we have, says Jesus, the more we are given!
God warns against the ways of the foolish repeatedly through His Word. The foolish often believe what they own is of great value and they struggle after personal wealth and professional power almost incessantly. Jesus says what they imagine they possess will not endure — rather it will be taken away.
James exhorts us to ask for the wisdom we may lack; if we ask in faith God is faithful to provide understanding.
Therefore, take care how you hear!
