In Matthew 4:4 Jesus says, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’”
I believe that it is extremely dangerous to attempt to summarize what is required for salvation in just a nutshell form. This is exactly what the Fundamentalists tried to do and where they got their name.
If we truly know and love God, then we will do everything we can to grow to love and know God more everyday. Grace is God’s gift to us. Grace is God’s favor and it carries with it enormous power. God’s grace justifies us, washes us, sanctifies us, makes us adopted sons and daughters, sets us free from committing sin, and provides our salvation. God’s grace is His very life within us.
Everyone understands the need for human relationships. We are made for relationships, and we are made especially for the ultimate relationship. That relationship is the relationship we have with the Father, Son, and Holy Spirit. The relationship we have with God is to know, love, and serve God with every fiber of our being. To know God is to accept and believe all that he has revealed to us. This knowledge of God enables us to properly love and obey Him as adopted sons and daughters within his household.
To know, love, and serve God with our whole mind, heart, soul, and strength cannot properly be defined by a minimum summarization of what is necessary to be saved. Jesus is our Lord and King, and not just our Savior. To be members of the household and to be heirs to the kingdom means that we live by grace through faith. We must live in the spirit by the grace of God. “To know the truth and to be set free” means to live in the grace of God as if there is no minimum for salvation. Total immersion in loving God has no bounds or limits.
We are pilgrims on the road that leads to heaven and we are to “work out our salvation in fear and trembling.”[Philippians 2:12]
