There is ‘the reason’, ‘the real reason’, ‘no reason’, and ‘the Holy Spirit reason’ for everything. The hard part is having the wisdom of which one to use at what time.
Matthew 10:16 says, “Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves.” We are not obligated to share ‘the real reason’ with everyone. Just ‘the reason’ will suffice.
Jesus goes on to tell us in the next four verses, “But beware of men, for they will deliver you up to councils and scourge you in their synagogues. You will be brought before governors and kings for My sake, as a testimony to them and to the Gentiles. But when they deliver you up, do not worry about how or what you should speak. For it will be given to you in that hour what you should speak; for it is not you who speak, but the Spirit of your Father who speaks in you.” This is when you must rely on ‘the Holy Spirit reason’.
At other times ‘the reason’ is not enough. We must speak ‘the real reason’. Genesis chapter 20 is all about this. Abraham told Abimelech that Sarah was his sister, which she was his half sister. But he should of been fully honest and told him that she was his wife.
Then there are times when we are to be silent and give ‘no reason’. Matthew 27:12-14 says, “And while He was being accused by the chief priests and elders, He answered nothing. Then Pilate said to Him, “Do You not hear how many things they testify against You?” But He answered him not one word, so that the governor marveled greatly.”
We must be careful to use ‘the real reason’ when it is mandated, because if we do not, we will be guilty of being a liar. At the other end of the spectrum, just because something is 100% truth doesn’t give us the right to speak it. For example, if someone is overweight, we do not have the right to speak it.
We must always be seeking wisdom on how to conduct ourselves as the Christians we should be.
