What is my responsibility towards those who are sick?

Mark 6:34Jesus saw the huge crowd as he stepped from the boat, and he had compassion on them because they were like sheep without a shepherd.

2 Corinthians 1:4He [God] comforts us in all our troubles so that we can comfort others. When they are troubled, we will be able to give them the same comfort God has given us.

God calls us to love, serve, and have compassion for all people.

James 5:13-18Are any of you suffering hardships? You should pray. Are any of you happy? You should sing praises. Are any of you sick? You should call for the elders of the church to come and pray over you, anointing you with oil in the name of the Lord. Such a prayer offered in faith will heal the sick, and the Lord will make you well. And if you have committed any sins, you will be forgiven. Confess your sins to each other and pray for each other so that you may be healed. The earnest prayer of a righteous person has great power and produces wonderful results. Elijah was as human as we are, and yet when he prayed earnestly that no rain would fall, none fell for three and a half years! Then, when he prayed again, the sky sent down rain and the earth began to yield its crops.

Whether a leader of the church or not, our responsibility is to pray for any brothers and sisters who are sick. Sin may be a factor that needs to be addressed, but the ultimate objective is not to find fault but to bring healing and help from God in this world of suffering.
