When the Lord asked Adam and Eve to be fruitful and to multiply in Genesis 1:26-28, He was not giving them any advice, rather the Almighty God was issuing a command to be obeyed from generation to generation. With the knowledge of this, we know for sure that the failure to bear fruit is a direct transgression of this divine decree.
Not only is the Almighty God interested in your spiritual fruitfulness, He also wants us to be fruitful physically and materially. God wants all His children should live in divine prosperity.
If you haven't surrendered your life to Christ, before anything else, it is necessary that you bear the fruit of repentance. This was the same thing the Lord Jesus told the Sadducees in Matthew 3:8. If however, you are already saved by grace, there are two types of fruit you must bring forth this year. The first is the fruit of the Spirit which was written in Galatians 5:23. The second part is the fruit of souls. It is important that you committed soul-winner.
It is already dangerous for anybody not to be fruitful, however it is even more dangerous for a believer. This is because the Lord Jesus says in John 15:2 that He will take away every branch in Him that doesn't bear fruit.
One benefit of soul-winning is sure answers to prayer. The reason the Lord had made you be alive up until this moment is that He is hoping to see you bear fruit.
