I think some of you may be familiar with Healing/blessing testimonies where a member would walk up to the stage and share a story about trials or hardships where somehow the Lord provided a miracle and got them out of their bad situation.
However, Jesus told some of the people He healed NOT to tell other people about their miraculous healing - Mark 7:36.
I think the reason why Jesus said such thing so that people would not be drawn into Christianity under the wrong motives such as healing,
Christianity didn't exist then - and plenty of people sought Jesus because they wanted healing.
Another reason why sharing accounts of Lord's miracle in our lives might be wrong is that it can be a source of pride for the person sharing the testimony. To let everyone know they have the Lord's favor upon them and righteous in their ways.
If anyone testifies "I was healed because I am righteous/especially blessed by God", that is wrong and misleading.
If people listening think "she was healed because she is righteous", they need further teaching, or have been taught wrongly.
So why put up with it when Lord is telling us NOT to do it
He's not telling us not to testify to the power, and love, of God.
Telling people, at that time, to keep quiet was one thing - they may have proclaimed him as the Messiah, tried to make him king by force or whatever, and his time had not come.
Giving testimony to the risen Christ, in a skeptical society, where people believe all sorts of things and none at all, is very different.
In my experience, people want hope. Many ask for prayer when loved ones are dying, even if they don't go to church. They don't like all the denominations, church ritual etc., but they want to hear about Jesus, and that they are loved unconditionally.
Saying "I know God is real because this is what he did for me", could be invaluable.
As long as you don't make it sound like you were good enough to receive from God or the answer to prayer was all your doing, it shouldn't be a problem.
I wrote this topic because I thought of sharing a testimony but also felt strongly NOT to. I felt strongly I might be doing a wrong thing because I might be only doing it to feed my pride even though it's not in my mind at all... The heart is deceitful above all things, and desperately wicked: who can know it? - Jeremiah 17:9
Why would testifying to God's power and love be a bad thing?
There is only one being that does not want us to glorify God so that others may believe.
Who can know your heart? God can, and does - and you should too.
Has it been given to God? Do you trust him to give you the right words to say? Do you regularly ask to be filled with the Spirit and ask him to glorify God through you? Jeremiah knew nothing about God living in us; we do.
