In our last Bible Study Mama (Judy) choose 2 Timothy 1:12 as one of her planks of faith for her ark.  Some of the wording I found a little confusing.  I am selecting it so you can help me understand it better.  I’ll start from verse 8.

2 Timothy 1:8-12 (New International Version)

8So do not be ashamed to testify about our Lord, or ashamed of me his prisoner. But join with me in suffering for the gospel, by the power of God, 9who has saved us and called us to a holy life—not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time, 10but it has now been revealed through the appearing of our Savior, Christ Jesus, who has destroyed death and has brought life and immortality to light through the gospel. 11And of this gospel I was appointed a herald and an apostle and a teacher.

12That is why I am suffering as I am. Yet I am not ashamed, because I know whom I have believed, and am convinced that he is able to guard what I have entrusted to him for that day.

In his letter, Paul urges Timothy to not have a “spirit of timidity” and to “not be ashamed to testify about our Lord” (1:7-8). He also entreats Timothy to come to him before winter, and to bring Mark with him (cf. Philippians 2:22). He was anticipating that “the time of his departure was at hand” (4:6), and he exhorts his “son Timothy” to all diligence and steadfastness in the face of false teachings, with advice about combating them with reference to the teachings of the past, and to patience under persecution (1:6–15), and to a faithful discharge of all the duties of his office (4:1–5), with all the solemnity of one who was about to appear before the Judge of the quick and the dead.

The wording in verse 12 that I am not clear on is, “I know whom I have believed, and am convinced that he is able to guard what I have entrusted to him for that day.”  Is Paul speaking of God as the one whom he believed?  If so then in the last part is Paul saying that he is convinced that God is able to guard what he, Paul, entrusted to God.  What did Paul entrust to God?
