To recognize God as Lord is to acknowledge that he is sovereign and supreme in the universe. To accept him as Savior is to accept his gift of salvation offered on the cross. To regard him as Father is to go a step further. Ideally, a father is the one in your life who provides and protects. That is exactly what God has done. Now it just falls to us to be trusting children. Let God give you what your family does not.
Having your family’s approval is desirable, but it’s not always possible, and it’s really not necessary for happiness. Jesus gave his family space and time and grace. And because he did, they changed. One brother became an apostle and others became missionaries. So don’t lose heart. God still changes families.
