The family of God includes all who have believed in him in the past, all who believe in the present, and and all who will in the future. We are all a family because we have the same Father. He is the source of all creation, the rightful owner of everything. God promises his love and power to his family, the Church. If we want to receive God's blessings, it is important that we stay in contact with other believers in the body of Christ. Those who isolate themselves  from God's family and try to go it alone cut themselves off from God's power.
 
God's love is total, says Paul. It reaches every corner of our experience. It is wide-it covers the breadth of our own experience, and it reaches out to the whole world. God's love is long-it continues the length of our lives. It is high-it rises to the heights of our celebration and elation. His love is deep-it reaches to the depths of discouragement, despair, and even death. When you feel shut out or isolated, remember that you can never be lost to God's love. For another prayer about God's immeasurable and inexhaustible love, see Paul's words in Romans 8:38, 39. So you see my brothers and sisters our ministry is extensive, it reaches to the highest mountain and to the lowest valleys, come join us! 
 
16 I pray that from his glorious, unlimited resources he will empower you with inner strength through his Spirit.
17 Then Christ will make his home in your hearts as you trust in him. Your roots will grow down into God’s love and keep you strong.
18 And may you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love is.
19 May you experience the love of Christ, though it is too great to understand fully. Then you will be made complete with all the fullness of life and power that comes from God. To our God and His Son, be Glory! Ephesians 3:16-19 (NTL)
