The Holy Spirit convicts folks of sin ! Folks either accept the truth that are sinners and REPENT or they reject the truth and stay in their sins NOT FORGIVEN. It is NOT works based based on man but based on the OBEDIENCE to the leadership and conviction of the Holy Spirit.
If folks OBEY and do as God commands how would you consider that works based salvation ?
Jesus did the work and offers salvation BASED on GRACE YOU either accept His work by repentance, FAITH in Him, follow Him where He leads or you reject His finished work by not putting your faith in Him.
God provided salvation YOU either accept or reject His salvation !
If You was starving and Someone brought you food which you rejected and you died from starvation would it be the person that brought you the foods fault that you starved to death OR would it be YOUR fault because you would NOT eat the food brought to you ?
Jesus taught in John 3:16 that whosoever believes in Him would NOT perish but have eternal life. NOW if you consider believing is a work based salvation YOUR argument is with Jesus NOT with those that believe His teachings,
