"We preach Christ crucified."

"We preach Christ crucified, unto the Jews a stumbling block, and unto the Greeks foolishness; But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. Because the foolishness of God is wiser than men; and the weakness of God is stronger than men. For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called: But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are: That no flesh should glory in his presence. But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: That, according as it is written, He that glorieth, let him glory in the Lord." 1 Corinthians 1:23-31
 
We preach with "the sword of the Spirit, which is the word of God."

"Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel." Ephesians 6:16-19
  
We "keep His commandments."

"Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the LORD your God which I command you." Deuteronomy 4:2

It is therefore a sin to accept any teaching o­n marriage that changes what God has already taught us about marriage in His commandments. All of the definitions of prohibited as well as allowable relationships have already been clearly defined in the Old Testament. There are no verses in the New Testament that redefine marriage even though some ministers make such claims. The misunderstandings concerning New Testament verses o­n marriage are the result of interpreting based o­n a cultural bias instead of based o­n what has already been clearly explained in the Old Testament.

Those who improperly redefine things about which God has already clearly spoken are false prophets.

"If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder, 2And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them; 3Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul. 4Ye shall walk after the LORD your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him. 5And that prophet, or that dreamer of dreams, shall be put to death; because he hath spoken to turn you away from the LORD your God, which brought you out of the land of Egypt, and redeemed you out of the house of bondage, to thrust thee out of the way which the LORD thy God commanded thee to walk in. So shalt thou put the evil away from the midst of thee." Deuteronomy 13:1-5
  
We're sinners, saved by grace.

"For all have sinned and come short of the glory of God." Romans 3:23

"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them." Ephesians 2:8-10 
 
We are o­n the Internet to "teach all nations." 

"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost" Matthew 28:19

We are not as heroic as some who have gone into very hostile territories. We don't claim to be heroes. We o­nly seek to do our best to do His will. We are going into all the world via the Internet. May God lead us when we are weak to follow His will no matter where it will lead us.
