If my people who are called by my name will humble themselves and pray and seek my face and turn from their wicked ways, I will hear from heaven and will forgive their sins and heal their land. (2 Chron. 7:14)(NLT)
Under God's covenant with Israel, there was a strong connection between sin and sickness. When the Lord commanded the Israelites to obey his laws, he promised to reward them by keeping them safe from many diseases. But these diseases were spiritual as much as physical. So here the Lord promised first to forgive his people, then to heal their land. We have also sinned against God in our thoughts and actions. But if we turn from our sin and humbly follow him, he will forgive us as well and heal us as his people. Let us praise God for healing and restoring us.
MERCIFUL GOD, we have harmed ourselves and others by neglecting your Word and living according to our own desires. Please forgive our sins, and help us to turn from our wicked ways. We thank and praise you for healing us. Amen
