Exodus 15:26 He (the Lord) said, "If you will listen carefully to the voice of the LORD your God and do what is right in his sight, obeying his commands and keeping all his decrees, then I will not make you suffer any of the diseases I sent on the Egyptians; for I am the LORD who heals you."
This verse tells us that even the Israelites had to do their part, and that we are expected to do our part. We can't fool ourselves that we are God children if we are not at least trying to do what God ask us to do!!... Our part is to do what is right in God's sight, not the sights of those around us, but God sight. Our part is to obey God's commands and keep his decrees... God also said here that he is our healer ... God heals our broken bodies and our broken spirits. God wants to take care of us we just have to do what he ask..and trust that God knows best. Remember the question isn't "Will my friends think I am making the right decisions will it make them happy or mad?" the questions is "Will God think I am making the right decisions will it make Him happy or glad?" When we start asking that question God will know that we are trying to please Him.
