And the chief priests and the elders and all the sanhedrin sought false witness against Jesus, in order to put Him to death. But they found none; yea, though many false witnesses came, they found none. But at last two false witnesses came up and said, This one said, I am able to destroy the temple of God and to build it in three days. And standing up, the high priest said to Him, Do you answer nothing? What is it that these witness against you? But Jesus was silent. And the high priest answered and said to Him, I adjure you by the living God that you tell us whether you are the Christ, the Son of God. Jesus said to him, You said it. I tell you more. From this time you shall see the Son of Man sitting on the right hand of power, and coming on the clouds of the heavens. (Matthew 26:59-64 MKJV)
but sanctify the Lord God in your hearts, and be ready always to give an answer to everyone who asks you a reason of the hope in you, with meekness and fear; having a good conscience, that while they speak against you as evildoers they may be shamed, those falsely accusing your good behavior in Christ.
(1 Peter 3:15-16 MKJV)
While you should always be prepared to give a reason for the hope that is in you, that doesn’t mean you have to answer every question a person asks you. Many have evil intentions, and sometimes, it’s best to remain silent.
It doesn’t matter what people think of you. God knows your heart, and what He knows is all that matters. Don’t worry about defending yourself. God will silence your accusers in due time.
When you speak, do it out of love—not hatred. If your words do not have the seal of God’s approval, it would be better not to say anything at all. Our words should be wrapped-up in God’s love; only then will we be able to affect positive changes.
