Logo Explained:

Black is the heart dead in sin deserving death and eternal hell in light of the absolute holiness of God and purity of His Love who Himself dwells in unapproachable light.

Red is the blameless blood of Jesus Christ, God's one and only Son, who lived a perfect life.

 White is the righteousness of Christ (His right standing before God His father) which is given to all who by God's Grace, turn from their sin and rebellion against God and trust not in their own works, goodness or philosophy to attain a harmonious relationship with God, but turn to God and accept Jesus' death as payment on their behalf for the punishment due themselves.

Green is the new life believers receive as the Spirit of Jesus takes up residence in each believing life.

Blue is the peace with God which the Cross of Christ has purchased for those who believe and for eternal heaven which all whose life is in Jesus will enjoy.

Philippians 2

Imitating Christ's Humility

¹If you have any encouragement from being united with Christ, if any comfort from his love, if any fellowship with the Spirit, if any tenderness and compassion, ²then make my joy complete by being like-minded, having the same love, being one in spirit and purpose. ³Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. ⁴Each of you should look not only to your own interests, but also to the interests of others.
⁵Your attitude should be the same as that of Christ Jesus:
    ⁶Who, being in very nature God,
       did not consider equality with God something to be grasped,
    ⁷but made himself nothing,
       taking the very nature of a servant,
       being made in human likeness.
    ⁸And being found in appearance as a man,
       he humbled himself
       and became obedient to death--
          even death on a cross!
    ⁹Therefore God exalted him to the highest place
       and gave him the name that is above every name,
    ¹⁰that at the name of Jesus every knee should bow,
       in heaven and on earth and under the earth,
    ¹¹and every tongue confess that Jesus Christ is Lord,
       to the glory of God the Father.

Shining as Stars

¹²Therefore, my dear friends, as you have always obeyed--not only in my presence, but now much more in my absence--continue to work out your salvation with fear and trembling, ¹³for it is God who works in you to will and to act according to his good purpose.
¹⁴Do everything without complaining or arguing, ¹⁵so that you may become blameless and pure, children of God without fault in a crooked and depraved generation, in which you shine like stars in the universe ¹⁶as you hold out the word of life--in order that I may boast on the day of Christ that I did not run or labor for nothing. ¹⁷But even if I am being poured out like a drink offering on the sacrifice and service coming from your faith, I am glad and rejoice with all of you. ¹⁸So you too should be glad and rejoice with me.  (NIV)
