You are called, Yes. You are graced, Yes. You have the Holy Ghost, Yes. I agree with you but there is a need to constantly strive for maturity. If will must become great in his sight of God, we must increase daily in the Knowledge of God.
It is time to rejoice. The devil is defeated, it will have no part in us any more.
God is Holy, He deserves to be worshipped. This is the only reason why we exist.
Man's promises can fail but God's word cannot. If he has spoken a thing to you, he will stand to watch over his words to bring it to pass. His Word is infallible because its content is Jesus.
God has not stopped calling men to partake in the misio dei. He chooses available vessels whom he equips and used to His glory. If a man is called, it does not mean that he is immune to challenges. But when storms of life come, we should believe that he is able to save us.
