Of course we believe in salvation by grace - but we follow the instructions given - to repent and be baptised for the remission of our sins and we shall be saved.
Just what is wrong with following instructions from Jesus?
We can each decide what we think - but does it really matter what any of us "think"? We are not giving the salvation. And, I would think that God gave us instructions on how we are to become Christians and receive his gift of salvation.
So - therefore, if Jesus told us to repent and be baptised and we would be saved.....just why should I delete part of this instruction and decide my way is sufficient?
Who are we pleasing by nickpicking? God or ourselves? Do we expect God to jump through our hoops to alter His instructions to win our belief? Don't think so.
Grace means "unmerited favor".
Even after we follow Jesus's instructions to believe and be baptized (confessing his name before men and repenting from our sins are scripturally taught as well), God by his grace and mercy (because no matter what we do, we don't receive salvation because we merited it), grants us the favor of becoming a member of the body of Christ, the church, for which Christ gave his life on the cross.
Hallelujah and praise his great name, that we who are sinners and of no account have been given this greatest of treasures by the GRACE OF GOD.
