Philippians 4:13 tells us that when we don’t have the strength to carry on,
the power and enabling of this great Friend is at our disposal: “I can do
everything through him who gives me strength.”
This relationship with Christ is so personal that not only can we speak with
Him but He also speaks with us and gives us the ability to hear His voice.
“My sheep hear my voice, and I know them, and they follow me” (John
10:27, KJV). This voice, though not audible, is nonetheless very real and
comforting. Who among us has not heard that inaudible voice leading,
comforting or reassuring them in the pains and confusion of life?
As His children the Lord Jesus gives us ears to hear His voice. “Then Jesus
said, ‘He who has ears to hear, let him hear’” (Mark 4:9). The unbeliever
may have a difficult time understanding this truth. For the believer,
however, we know that voice of God in our spirit. We sense His directing
and comforting presence and hear His Spirit speak to our Spirit. What an
amazing thing it is to know these words of comfort and reassurance in our
spirit.
It is for this reason that Spirit of Christ can testify “with our spirit that we
are God's children” (Romans 8:16). As husbands and wives, we know how
important it is to be reassured of the love and affection of our spouse. Even
as friends, our relationship needs to be reaffirmed from time to time. God
knows this human need and reassures us of His relationship by
communicating with our spirit. He whispers: “You are mine” into our
spiritual ears. He reassures us of our relationship with Him and of His
presence in our lives.
This reassurance of the Spirit is very personal. Charles Spurgeon, in a
sermon entitled “Full Assurance” said this:
Nothing short of a divine testimony in the soul will ever content the
true Christian. The Spirit of God must Himself after a supernatural
sort speak to our conscience and to our heart or else peaceful and
quiet our spirit can never be. (Spurgeon, C.H., “Full Assurance” found at
