"Simply let your 'Yes' be 'Yes,' and your 'No,' 'No'; anything beyond this comes from the evil one." (Matthew 5:37)
Maybe I'm a bit old-fashioned. I was raised by my Daddy that a man's word is his bond and a handshake is just as good. Even before I was a believer I heard that if you tell someone you'd be somewhere or do something you better follow through.
Sadly, I am not seeing that a lot today among some brothers and sisters in Christ. Too often, I see people being led "by the Spirit" in making their decisions. This would be okay if they stood by them. However one week someone will say they will be somewhere or do something, and the next they change their mind. If the Spirit is leading ,who changed their mind: you or the "Spirit"?
James 4:13-16, "Come now, you who say, 'Today or tomorrow we will go to such and such a city, and spend a year there and engage in business and make a profit.' Yet, you do not know what your life will be like tomorrow. You are just a vapor that appears for a little while and then vanishes away. Instead, you ought to say, 'If the Lord wills, we will live and also do this or that.' But as it is, you boast in your arrogance; all such boasting is evil."
As believers we should be known for our integrity, not just before the world but amongst fellow believers as well. It is time for the flightiness and fidgeting among the body of Christ to cease and for people to commit where the Lord calls them. We should not be like butterflies, flitting from thing to thing (or experience to experience) looking for something more exciting. We should stay the course God has set us on unless He tells us to move.
If the Lord does call YOU to do something and you know it is your calling, then don't try to pass it off on someone else. Seek the wisdom of the Lord. Do what He tells you and follow through on your word!
