John 12:17-19 WEB
The multitude therefore that was with him when he called Lazarus out of the tomb, and raised him from the dead, was testifying about it.  For this cause also the multitude went and met him, because they heard that he had done this sign.  The Pharisees therefore said among themselves, “See how you accomplish nothing. Behold, the world has gone after him.”
Jesus did a wonderful miracle, he raised Lazarus from the dead. Not only did he raise him, but Jesus did it after Lazarus was buried and dead for four days. The people that were there to grieve for Lazarus saw what Jesus did. And now, they were repeating the story and causing many to look for Jesus. The Lord, through his ministry commonly told people to keep their miracles a secret (Mat 9:29-30). But this sign was too big to keep silent. So, they testified, and many came to Christ.
How do we know when we are testifying and when we are bragging? That is a huge issue in modern society. We live in a time when self-promotion is rampant and often leads to success. Yet the word teaches us not to boast about our accomplishments (1 Sam 2:3). It can even be a boast to tell what God is doing in our lives. When we are right with God, we do not have to prove we are right with God. That comes from ego and self-promotion. We do not have to brag about our blessings. We should brag on God alone. He is our boast.
We can often tell when God has intervened in someone’s life. God will begin to fix what is broken and line up a believer with their destiny. But having healing or destiny is not something to brag about. Having a destiny in Christ should lead to our silence. We may at appropriate times share our calling with others. After all, we still need people even when we are solidly in Christ. But in general, it is not something we should be bragging about. Rather, we should treasure the miracles and share them when led by the Holy Spirit, so they lead others to Christ.
Lord, give me the wisdom to see when I am testifying and leading others to you, and when I am bragging and harming others. Take pride and ego away, Lord, and leave a tender heart prepared to receive from you. Help me receive the wisdom to keep silent. Lead me by your Holy Spirit and let my only boast be you, Lord. In Jesus’ name, amen.
