My mouth will tell of your righteous acts, of your deeds of salvation all the day, for their number is past my knowledge. With the mighty deeds of the Lord God I will come; I will remind them of your righteousness, yours alone. O God, from my youth you have taught me, and I still proclaim your wondrous deeds. So even to old age and gray hairs, O God, do not forsake me, until I proclaim your might to another generation, your power to all those to come.
Jesus said, “Go into all the world and preach the gospel to every creature” (Mark 16:15).
Therefore do not be ashamed of the testimony about our Lord, nor of me his prisoner, but share in suffering for the gospel by the power of God, who saved us and called us to a holy calling, not because of our works but because of his own purpose and grace, which he gave us in Christ Jesus before the ages began, and which now has been manifested through the appearing of our Savior Christ Jesus, who abolished death and brought life and immortality to light through the gospel, for which I was appointed a preacher and apostle and teacher, which is why I suffer as I do. But I am not ashamed, for I know whom I have believed, and I am convinced that he is able to guard until that Day what has been entrusted to me.
2 Timothy 2:15
Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.
Matthew 28:19-20 ESV
Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
Psalms 96:3 NKJV
“Declare His glory among the nations, His wonders among all peoples.”
