<p>15:11 <i>Whether I or they</i>- If it is God's grace which motivates all preaching work, then it matters not which channel was used- whether Paul or other apostles. This is what he has already laboured in chapter 1, explaining that it matters not who preached to a person or baptized them. All was a manifestation of the essential grace of God, and the channel used should not make any difference.</p><p><i>So we preach and so you believed</i>- &ldquo;Our preaching&rdquo; and &ldquo;your faith&rdquo; are paralleled in 1 Cor. 15:14. We see here the degree to which individual initiative in preaching is related to the faith and salvation of others. This is the force of the word &quot;so&quot;. Salvation is in some sense dependent upon third party efforts (Mk. 2:5). God has delegated His work to us, and to some degree, the extent of its progress depends upon us. Note that faith or belief is predicated upon hearing the Gospel of Christ's death and resurrection. Not upon following the detailed scientific arguments made for creationism, nor by any other attempt to make science 'prove God'.</p>
