Both doctrines are true…it’s like Christ was 💯 God and 💯 man, simultaneously.
God is 💯 sovereign and He has given man 💯 freewill.
The gift of salvation is 💯 from God so no man can boast and we must receive it 💯 by faith.
Like James said, works without faith and faith without works are incomplete but they are both 💯 simultaneously, two sides of the same coin.
That how I see salvation. We are 💯 predestined & called yet we must respond, accept and cherish the gift of God 💯.
