2 Corinthians 6:1 We then, as workers together with Him also plead with you not to receive the grace of God in vain.
You may be asking “how can I receive a free gift in vain?” And the obvious answer would be that you cannot because it is a gift that is freely available to us.
I believe that people still do take the word of God, the Gospel, the Scriptures, our bibles, whatever you would call it, in vain. They read but don’t accept. They read but don’t believe it all.
God has given us His Word because it is the truth. We cannot presume to understand it all and need constant guidance from The Holy Spirit to show us what it means.
Continue receiving that guidance with grace.
