"Conduct yourselves with wisdom toward outsiders, making the most of the
opportunity.  Let your speech always be with grace, seasoned, as it were,
with salt, so that you may know how you should respond to each person."
Colossians 4:5-6

These verses are similar to 1 Peter 3:15 in that it speaks of our
conduct, both actions and words before non Believers.
The Apostle Peter tells us to be able to give an account for our hope with
gentleness and reverence. In today's verses the Apostle Paul says that our
conduct, that is our walk, should be 'with wisdom toward outsiders (non
Believers) making the most of the opportunity' and our 'speech always
with grace.'

Scripture tells us of gifts that God has given as seen in Ephesians 4:7-14
(read the account for yourselves). One of those is the gift of evangelism.
We know that history has had many great evangelist and I thank God for 
them,
but you and I are also called to live our lives in such a way that non
Believers will see a difference and desire after the same. The above verses
of Peter and Paul state as much.

If Galatians 2:20 be our portion as was Paul's,
"I have been crucified with Christ; and it is no longer I who live, but
Christ lives in me; and the life which I now live in the flesh I live by
faith in the Son of God, who loved me, and delivered Himself up for me."
can we not say that our Lord Jesus Christ is still in the world seeking and
saving souls?

How then should we conduct ourselves (walk) in this world that is not God
fearing, but corrupt? Scripture tells us! We are to:

*Walk in newness of life (different from the old way of life):
"Therefore we have been buried with Him through baptism into death, in 
order
that as Christ was raised from the dead through the glory of the Father, so
we too might walk in newness of life." Romans 6:4

"Therefore, if anyone is in Christ, he is a new creation; old things have
passed away; behold, all things have become new." 2 Corinthians 5:17

*Walk by faith:
"For we walk by faith, not by sight."
Sight: EIDOS in the Greek is 'the physical appearance of things which are
set in contrast to that which directs faith...the believer is guided...by
what he knows to be true though it is invisible.' "Vine's Expository
Dictionary"

*Walk by the Spirit:
"But I say walk by the Spirit, and you will not carry out the desire of the
flesh." Galatians 5:16 (Our behavior then will be 'other worldly.')

*Walk worthy of your calling:
"I...entreat you to walk in a manner worthy of the calling with which you
have been called, with all humility and gentleness, with patience, showing
forbearance to one another in love." Ephesians 4:1-2

*Walk in love:
"Walk in love, just as Christ also loved you and gave Himself up for us, an
offering and a sacrifice to God as a fragrant aroma." Ephesians 5:2

*Walk in the light yields fellowship:
"But if we walk in the light as He Himself is in the light, we have
fellowship with one another, and the blood of Jesus, His Son cleanses us
from all sin." 1 John 1:7

*Walk in Christ likeness:
"The one who says he abides in Him (Christ Jesus) ought himself to walk in
the same manner as He walked. 1 John 2:6

I close with Paul's admonition to all Believers in Ephesians 5:15-16,
"Therefore, be careful how you walk, not as unwise men, but as wise, making
the most of your time, because the days are evil."

Our walk and our talk must be the same and God will prepare hearts to 
listen
as we share the Good News. May the Holy Spirit lead and guide us in the way
of needy lost souls whose hearts He has prepared to receive the Gospel of
Jesus Christ. Salvation is from, through, in and by our Mighty God alone!
All praise to Him. Amen
