The gift of speaking in tongues is not for everybody .
When you give your life to christ you receive all the blessings of the holly spirit but that doesn't mean that you must be speaking in tongues before you will be known ti have the spirit of God in us.
When God made us he gave us all we need but we disappointed him by doing what he said we should not do by eating the forbidden fruit.
He sent his son to reconsile our deeds with him.
