Nevertheless, the firm foundation of God stands, having this seal, "The Lord knows those who are His," and, "Everyone who names the name of the Lord is to abstain from wickedness."2 Timothy 2:19(NASB)
The spread of false doctrine in the Church is likened to a cancer that spreads and infects the physical body, which finally dies. The Church of God, individually and corporately, should rather stand fast on the firm foundation of Christ Jesus our Lord and should shun every kind of evil thought, unkind word, ungracious action, or selfish motive.
And so we are called to be faithful soldiers who obey their commander-in-chief, determined athletes who run with patience the race set before them, industrious farmers who faithfully plant and tend their crops to harvest, diligent workmen who treasure God's Word in their hearts, and strong buildings which stand firm on their immovable foundation - and that Rock is Christ.
God alone knows the thoughts and intentions of every man. He can read the inner thoughts of our hearts and discern our secret motives, and God knows all those that belong to Him.
And everyone who calls themselves Christians, all those who are called by His name, are instructed to abstain from every kind of evil but in Christ's strength, to diligently pursue that which is good while relying in utter dependence upon the Lord.
Heavenly Father, thank You that You sent the Lord Jesus to be the firm foundation upon which I am to stand. Thank You that I am Your child and that You know everything about me. Help me, I pray, to abstain from every kind of evil, and help me to run the race that is set before me, looking to Jesus, the Author and Finisher of my faith. In Jesus' name I pray, AMEN.
