Paul is correct; it is you guys who get it wrong. The Grace of God enables our salvation; it guarantees our inheritance to salvation in Christ.
Yet if we walk away as the Prodigal Son did, we forfeit our inheritance. It is not until we return, as he did, beating our breasts in sorrow and plead for forgiveness, that we will gain that inheritance. The tax collector in the back of the church, not the Gnostic Pharasiacal Reformed who claim knowledge, surety and the elevated position as presaved in the Kingdom of Heaven.
Christians have the hope of Paul, not the surety of the Calvinist select. You may accuse the Church of claiming to give salvation but that is not the Church's position. We begin with Grace; without Grace there is nothing. With Grace, we have faith, hope, and love.
Not arrogant coronation of the Elect.
Mark ...that is a weak grace...when it is subject to the will of man and not the sovereign God.
Salvation is a gift from God which He freely bestows on those who receive it through faith. We are sealed with the promised Holy Spirit given us as a guarantee until the day of our redemption.
God is not an Indian giver.
When we become His child we are born into His family and He will not disown us if we slip and sent us to hell for the least little infraction just because we're human.
John 10:28-30 28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand. 29My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand. 30 I and the Father are one."
Philippians 1:6
And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.
