Okay, the context begins with Titus 1:1-3, "Paul, a servant of God and an apostle of Jesus Christ to further the faith of God's elect and their knowledge of the truth that leads to godliness--in the hope of eternal life, which God , who does not lie, promised before the beginning of time, and which now at his appointed season he has brought to light through the preaching entrusted to me by the command of God our Savior."
We might note that these words are akin to what Paul wrote in Ephesians 1:3-10, and the command occurred on the road to Damascus.
After giving instructions regarding elders, rebuking anti-Christians and teaching Christians including slaves, Paul said the following that is further context for the verses you cited, "The grace of God has appeared that offers salvation to all people" (Tit. 2:11). This statement is akin to John 3:16, 1Timothy 2:3-4 and 2 Peter 3:9.
Then after a brief instruction regarding subjection to rulers, Paul made the comment you cited (Tit. 3:4-7), "When the kindness and love of God our Savior appeared, 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, whom he poured out on us generously through Jesus Christ our Savior, so that being justified by grace , we might become heirs having the hope of eternal life."
We might note that the phrase "God our Savior" is found also in 1 Tim. 3 and is echoed by the phrase "JC our Savior". God's grace is mentioned in Ephesians 2:8-10, but the most extensive context for the meaning of this term is Romans 3:21-5:11.
