In Second Timothy One verse 14 we can read this…Guard [with greatest care] and keep unchanged, the treasure [that precious truth] which has been entrusted to you [that is, the good news about salvation through personal faith in Christ Jesus], through [the help of] the Holy Spirit who dwells in us.
Second Peter One One says…Simon Peter, a bond-servant and apostle (special messenger, personally chosen representative) of Jesus Christ, To those who have received and possess [by God’s will] a precious faith of the same kind as ours, by the righteousness of our God and Savior, Jesus Christ:
Your faith has been entrusted to you and received by you and we are told to guard it and keep it unchanged. Now read Galatians 2:6-8
Galatians 2:6-8 – Amplified Bible
6 But from those who were of high reputation (whatever they were—in terms of individual importance—makes no difference to me; God shows no partiality—He is not impressed with the positions that people hold nor does He recognize distinctions such as fame or power)—well, those who were of reputation contributed nothing to me [that is, they had nothing to add to my gospel message nor did they impose any new requirements on me].7 But on the contrary, they saw that I had been entrusted with the gospel to the uncircumcised (Gentiles), just as Peter had been [entrusted to proclaim the gospel] to the circumcised (Jews); 8 (for He who worked effectively for Peter and empowered him in his ministry to the Jews also worked effectively for me and empowered me in my ministry to the Gentiles).
The Holy Spirit has work for each of us to do. What have you been entrusted with?
