When you got born again, and received the holy Ghost to dwell in you, he shed his love in your heart, this means you can love just like God loves- he has given you a new heart:

“…the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.” Romans 5:5
The Bible says:

“We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.” 1 John 3:14
The carnal man does not walk in love:

“For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?” 1 Corinthians 3:3

The spiritual man walks in love absolutely, his response to any brother who might have missed his way is restoration not condemnation:

“Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.” Galatians 6:1

Just like Jesus:

“When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee? She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.” John 8:10-11
