The Bible is full of promise from God to us yet before Jesus went back to heaven, He told His disciples to “wait for the Promise of the Father”. (Acts 1:4) There are thousands of promises in the Bible, so which promise was He referring to?
The early church knew which promise Jesus was referring to because He had told His disciples, “Do not leave Jerusalem, but wait for the Promise of the Father, which you have heard Me speak about. For John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.” (Acts 1:4–5) Jesus was referring to the baptism in the Holy Spirit with speaking in tongues. (Acts 2:1–4)
Jesus wants you to know the value of the Promise of the Father because He said, in Acts 1:8 But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.”
He did not say, “You shall do witnessing,” but “You shall be witnesses”. In other words, your very person will be a witness to Him!
This is because the power you receive when you are baptized in the Holy Spirit is the same power that so anointed Peter that the sick were laid on the streets for his shadow to fall on them and heal them. (Acts 5:15) Even handkerchiefs and aprons from Paul’s body were so saturated with the anointing of the Spirit that when they touched the sick, people witnessed diseases and evil spirits leaving the sick! (Acts 19:12)
When you are baptized in the Holy Spirit, you will be a witness to others that no problem, trial, disease or sickness is a match for the power of the Spirit in you! To be baptised means to be submerdged. Like a sponge after been soaked in water. Our lives should be in a way where you can’t but notice the effect of the Holy Spirit living inside of us!
