With commitment the focus is on what you are giving into the relationship. With surrender the focus is on what you are giving up for the relationship. This may be a surprise to most but the bible never uses either of those words to describe our relationship with God. The word that is used is submission which literally means "voluntary cooperation."
Commitment proclaims, "My utmost for His highest." Cooperation says, "His highest is fun!" Surrender says, "More of Him & less of me." Cooperation says, "Us." Commitment burdens you. Surrender takes away your value. Voluntary Cooperation gives you value without giving you burden. With cooperation the focus is not on what you are giving to God or giving up for God but on what God is giving you!
Commitment thinks God is demanding, "Do my will." Surrender thinks God is demanding, "Deny yourself." Cooperation knows God is offering, saying, "I've thought of some great things we can do today. What do you want to do with me?"
Synonyms for commitment are obligation, duty, adherence, dedication, devotion, responsibility, liability, promise, vow, oath, pledge.
Synonyms for surrender are despair, defeatism, giving up, quit, cave in, throw in the towel, succumb, resign, loss.
Synonyms for cooperation are unity, teamwork, collaboration, help, assistance, participation, responsiveness, helpfulness.
Commitment is the language of the law. Surrender is the language of shame. Cooperation is the language of loving relationship. Religion has added, removed, or reinterpreted words but God chose wisely the words He used. He doesn't demand commitment or surrender. He lovingly requests cooperation both for salvation and day to day living.
Remember we are His children & His friends. Our Father just wants to have a good time loving His kids & bringing more people into the family. He says, "Wanna go do something today for your older brother? Wanna go do something today for your younger sister?" No one in His family is looked down upon for opting out. They are loved just the same. Yes they are missing out on a good time with the Father & the family but they will be treated no worse by the Father even if they never want to cooperate. He will love us into participation & cooperation. That is our Father's unconditional love. Everyone is free & everyone is favored. Who could ask for anything more?
