As I understand, it is more of the fruit of the spirit as in Galatians 5, growing in character. Jesus promised that those who abide in Him will bear "much" fruit:

(John 15:5 NASB) “I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing.

Also, witnessing to others is much like planting seeds. Some sow, some water, some reap. The people who do come to the Lord may because of a word or act of someone long ago:

Jesus said: (John 4:36–37 NASB) “Already he who reaps is receiving wages and is gathering fruit for life eternal; so that he who sows and he who reaps may rejoice together. “For in this case the saying is true, ‘One sows and another reaps.’

Paul wrote: (1 Corinthians 3:6–8 NASB) I planted, Apollos watered, but God was causing the growth. So then neither the one who plants nor the one who waters is anything, but God who causes the growth. Now he who plants and he who waters are one; but each will receive his own reward according to his own labor.

Summary: The fruit we bear is in our own character development may result in us being a positive witness for the Lord. Others may come to know Christ through us, but as far as I know, it is not a requirement for our salvation. It is a free gift to those who believe in Jesus Christ (Romans 10:9).
