If I know something about someone or some situation and at the very least neglect to pray to God about it, God has every right to hold me responsible. That problem, that incident, whatever it is you saw was actually God showing you. And in a court of law, things need to be stated by those who know them. Pertinent things that could ensure justice is accurately served. How much more so in the Kingdom of God? The word also refers to dereliction of duty. When someone entrusts to you the performance of tasks that require an exclusive or rare skill set, and somehow you neglect to do them, it goes without saying that...they simply won't get done. In some places, it's grounds for dismissal. Others still, it's punishable with imprisonment. And misprision could simply connote a mistake. Any way you look at it, God will help you do the right thing when the time comes.
And don't worry, God's been training you whether you realize it or not. He wastes nothing.
"Take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost." (Mark 13:11b) This is Jesus talking.
"When Pilate therefore heard that saying, he was the more afraid (referring to the Pharisees' accusations against Him); And went again into the judgment hall, and saith unto Jesus whence art Thou? (where are You from?) But Jesus gave Him no answer." (John 19:7-8) This is Jesus not talking.
"Fearfulness hath surprised the hypocrites" (Isaiah 33:14)
Here's the thing though. If you have some overarching or underlying notion you're called to do something that hasn't yet been revealed, then keep going. Keep reading, keep studying, keep worshipping. When God sees you're ready, He'll unveil you to those you're intended to influence. And if we're afraid, could there be, as the above verse identifies, some vestige of hypocrisy in our hearts keeping us from stepping into this destiny? Because unless we learn and live the lessons of our own lives, God can't then use us to heal that segment of the Body of Christ, of humanity. He wants to. Use us, that is.
"He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much." (Luke 16:10)
Think about all the major players in the Old Testament. Each had their mistakes, their foibles and follies and failings. Yet look! Jesus came. He did what He had to do and those who came after got the job done as well. We have a church, a worldwide body of believers comprising the family of God. Even after all the mistakes and mishaps and mess-ups. Really, some horrible stuff has conspired to derail the great plan of God, yet nothing ultimately can. The question is, where do we fit in all of this?
"For we are His workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them." (Ephesians 2:10)
Don't worry about failing. God's love and mercy and timing are big enough to encapsulate all our hopes and fears and failings. And if you've failed to act or speak when the occasion called for it, know that God has your second chance in His hands. He will give you as many second chances as He gives you the grace to ask for them. This, however, isn't something to run roughshod over. It should inspire a moment of sobriety and calm. And know that the more we look to and walk with God in worship and praise, the more we'll find that everything He has for us will come in the everyday, ordinary ways. You'll achieve that calling yet!
"Being confident of this very thing, that He that hath begun a good work in you will perform it until the day of Jesus Christ." (Philippians 1:6)
