God has acted so that men can be saved. In the cross and the resurrection He has provided the means of salvation, and He is not willing that any perish but that all come to repentance.
The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for all to come to repentance.
Faith and repentance are man's responsibility to take advantage of the means of salvation which God has provided.
And Jesus came up and spoke to them, saying, "All authority has been given to Me in heaven and on earth. "Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age."
"Therefore having overlooked the times of ignorance, God is now declaring to men that all everywhere should repent, because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead."
If God has provided the means of salvation, and if he is not willing that any of us perish but for all to come to repentance then we must have the ability provided by Him to come to repentance. The book of Acts is filled with examples of men coming to repentance.
Now when they heard this, they were pierced to the heart, and said to Peter and the rest of the apostles, "Brethren, what shall we do?" And Peter said to them, "Repent, and let each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit. "For the promise is for you and your children, and for all who are far off, as many as the Lord our God shall call to Himself." And with many other words he solemnly testified and kept on exhorting them, saying, "Be saved from this perverse generation!" So then, those who had received his word were baptized; and there were added that day about three thousand souls.
And while he was clinging to Peter and John, all the people ran together to them at the so-called portico of Solomon, full of amazement. But when Peter saw this, he replied to the people, "Men of Israel, why do you marvel at this, or why do you gaze at us, as if by our own power or piety we had made him walk? "The God of Abraham, Isaac, and Jacob, the God of our fathers, has glorified His servant Jesus, the one whom you delivered up, and disowned in the presence of Pilate, when he had decided to release Him. "But you disowned the Holy and Righteous One, and asked for a murderer to be granted to you, but put to death the Prince of life, the one whom God raised from the dead, a fact to which we are witnesses. "And on the basis of faith in His name, it is the name of Jesus which has strengthened this man whom you see and know; and the faith which comes through Him has given him this perfect health in the presence of you all. "And now, brethren, I know that you acted in ignorance, just as your rulers did also. "But the things which God announced beforehand by the mouth of all the prophets, that His Christ should suffer, He has thus fulfilled. "Repent therefore and return, that your sins may be wiped away, in order that times of refreshing may come from the presence of the Lord; and that He may send Jesus, the Christ appointed for you, whom heaven must receive until the period of restoration of all things about which God spoke by the mouth of His holy prophets from ancient time. "Moses said, 'THE LORD GOD SHALL RAISE UP FOR YOU A PROPHET LIKE ME FROM YOUR BRETHREN; TO HIM YOU SHALL GIVE HEED in everything He says to you. 'And it shall be that every soul that does not heed that prophet shall be utterly destroyed from among the people.' "And likewise, all the prophets who have spoken, from Samuel and his successors onward, also announced these days. "It is you who are the sons of the prophets, and of the covenant which God made with your fathers, saying to Abraham, 'AND IN YOUR SEED ALL THE FAMILIES OF THE EARTH SHALL BE BLESSED.' "For you first, God raised up His Servant, and sent Him to bless you by turning every one of you from your wicked ways."
