Acts 4:12 - Jesus is Sovereign

Jesus is the only One who can save people.
His name is the only power in the world
that has been given to save people.
We must be saved through him.
Acts 4:12 (NCV)

Jesus saith unto him,
I am the way, the truth, and the life:
no man cometh unto the Father, but by me;
John 14:6 (KJV)

I, even I, am the LORD;
and beside me there is no saviour.
Isa 43:11 (KJV)

Many people react negatively to the fact that there is no other name than
that of Jesus to call on for salvation. Yet this is not something the church
decided; it is the specific teaching of Jesus himself (John 14:6). If God
designated Jesus to be the Savior of the world, no one else can be his
equal. Christians are to be open-minded on many issues, but not on how we
are saved from sin. No other religious teacher could die for our sins; no
other religious teacher came to earth as God's only Son; no other religious
teacher rose from the dead. Our focus should be on Jesus, whom God offered
as the way to have an eternal relationship with himself. There is no other
name or way!  [Life Application SB]

In receiving the word, we receive Christ. And only those who thus receive
His words are building upon Him. "Other foundation can no man lay than that
is laid, which is Jesus Christ." 1 Corinthians 3:11. "There is none other
name under heaven, given among men, whereby we must be saved." Acts 4:12.
Christ, the Word, the revelation of God,--the manifestation of His
character, His law, His love, His life,--is the only foundation upon which
we can build a character that will endure. . . . As you receive the word in
faith, it will give you power to obey. As you give heed to the light you
have, greater light will come. You are building on God's word, and your
character will be builded after the similitude of the character of Christ.

Jesus is the only source of salvation, the only one able to forgive sins and
provide new spiritual life. [Victor Bible Reader's Companion]

We are undone if we do not take shelter in this name, and make it our refuge
and strong tower; for we cannot be saved but by Jesus Christ, and, if we be
not eternally saved, we are eternally undone (v. 12): (Matthew Henry's
Commentary)
