He certainly was a believer in the total depravity of man- John 2:23 -
Now when he was in Jerusalem at the Passover Feast, many believed in his name when they saw the signs that he was doing. 24 But Jesus on his part did not entrust himself to them, because he knew all people 25 and needed no one to bear witness about man, for he himself knew what was in man.
He taught about election- John 6:44 - No one can come to me unless the Father who sent me draws him.
He taught limited atonement- John 17:1,2 - When Jesus had spoken these words, he lifted up his eyes to heaven, and said, “Father, the hour has come; glorify your Son that the Son may glorify you, 2 since you have given him authority over all flesh, to give eternal life to all whom you have given him."
He taught and modeled irresistible grace in the life of Paul- Acts 9:1-6
But Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest 2 and asked him for letters to the synagogues at Damascus, so that if he found any belonging to the Way, men or women, he might bring them bound to Jerusalem. 3 Now as he went on his way, he approached Damascus, and suddenly a light from heaven shone around him. 4 And falling to the ground he heard a voice saying to him, “Saul, Saul, why are you persecuting me?” 5 And he said, “Who are you, Lord?” And he said, “I am Jesus, whom you are persecuting. 6 But rise and enter the city, and you will be told what you are to do.”
He taught the perseverance of the saints- John 10:27-30 -
My sheep hear my voice, and I know them, and they follow me. 28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand. 29 My 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.
