It is important and helpful to understand the place of the Name in the plan of salvation, and its relation to the believer in his Christian life.
Matthew 1:21,23 The Name “Jesus” (Yeshua in Hebrew) is inseparably connected with salvation. Acts 4:12.
It is the one Name through which the sinner approaches the Great Father God, the one Name that gives him a hearing, the one Name that unveils the mediatorial ministry of Jesus.
His Name is an essential component of Baptism.
“Baptizing them into the Name of the Father and of he Son and of the Holy Spirit.”
“Repent ye and be baptized every one of you in the Name of Jesus Christ unto the remission of sins, and ye shall receive the gift of the Holy Spirit.”
Therefore, not only are we saved by the Name, but the believer is baptized into the Name, and we receive the gift of the Holy Spirit on the ground of that Name.
Jesus gives us these promises of the use of His Name in prayer:
We see that He fulfills His promise in example after example in the New Testament.
Peter healed a man born crippled in the Name of Jesus. Acts 3:1-6.
Paul casts out a demon in this Name. Acts 16:18.
The Name has great power for us believers today: Matthew 18:20.
The assemblies were taught that when they gathered together, they gathered around that Name.
In Colossians 3:17, the early disciples were taught to do all things in that Name.
Ephesians 5:20 enjoins that we always give thanks for all things in that Name.
Hebrews 13:15. Make confession to His Name.
James 5:14. Anoint the sick in that Name.
1 John 3:23. Believe in the Name of His Son Jesus Christ.
We can see that the Name of Jesus touched every phase of the life of the church and of the individual believer in those early days. It filled a place of their thoughts, their prayers, their preaching, of which most of us are ignorant today.
