Without the Holy Spirit
Without the Holy Spirit, we do have the "inability" to get saved. Without the Holy Spirit is TOTAL DEPRAVITY".
The Holy Spirit is the only person that can quicken people to be saved. 1 Corinthians 2:14 The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned. Acts 7:51 "You stiff-necked people, with uncircumcised hearts and ears! You are just like your fathers: You always resist the Holy Spirit! 1 Thessalonians 4:8 Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit.
The Holy Spirit convicts. Romans 5:5 And hope does not disappoint us, because God has poured out his love into our hearts by the Holy Spirit, whom he has given us. 1 Corinthians 6:19 Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own. 1 Thessalonians 1:5 because our gospel came to you not simply with words, but also with power, with the Holy Spirit and with deep conviction. Titus 3:5 he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit.
Without the Holy Spirit, we will not REPENT. We cannot repent on our own. We are to repent with the help from the Holy Spirit who will help us TRANSFORM us to the image of God.
Here's another reference regarding "without the Holy Spirit is TOTAL DEPRAVITY" Reading Mark, something caught my eyes a long time ago when Jesus was asking a question. I always wondered WHY He was asking that question. What question was Jesus asking? Jesus asked, "Which is more difficult, to heal disease or forgive sin?" (Mk. 2:9). Conversion happens when the Holy Spirit convicts people to feel desperate over the disease of sin and start repenting. There's no self-will or self-centeredness, and no acknowledgement of rights or claims involved of mind without the Holy Spirit. We can't be saved without the Holy Spirit and with regard to salvation, we are touched and cleansed from SINS after the Holy Spirit convicts us to repent and come Christ in faith, only in terms of the disease of sin which is worse than the diseases.
Can't get much clearer than that.
Oh.. there is still freewill...
People can either acknowledge the conviction of the Holy Spirit to repent and come to Christ in faith.
OR
Acts 7:51 "You stiff-necked people, with uncircumcised hearts and ears! You are just like your fathers: You always resist the Holy Spirit! 1 Thessalonians 4:8 Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit.
Are people willing to acknowledge the conviction of the Holy Spirit is the question. Since sin often ignores the Holy Spirit... not many will acknowledge. People will (as 2 Timothy 3:7 says) always learning but never able to acknowledge the truth.
