{3 Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints. 4 For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into lewdness and deny the only Lord God and our Lord Jesus Christ. Jude 1:3-7}
We should be offensive and defensive towards False Teachings.
However, we are to Be Loving; {for these are the two greatest commandments; Jesus answered him, “The first of all the commandments is: ‘Hear, O Israel, the LORD our God, the LORD is one. 30 And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment. 31 And the second, like it, is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.” Mark 12:29-30}
Although it is okay to judge a man’s actions, if done in love and by God’s truth not our own standards; it is not okay to judge a mans heart. So while we MUST rail against the False Teaching and errors on essential doctrine, we must remember that if the person is a professed believer, we must hope the best for that person in love.
We are NOT to compromise the essentials, but should love all of our brothers and sisters in Christ even if we differ on secondary, non-essential doctrinal issues. We should approach a brother or sister who may be reinforcing bad teaching, in hopes that they are not aware of their error.
I’m not by any means using the old cliché, “hate the sin, not the sinner”, but what I am saying is that we should be growing in all the fruits of the spirit, and should be very careful not to sin against others and God when we contend for the faith.
{13 Watch, stand fast in the faith, be brave, be strong. 14 let all that you do be done with love. 1 Corinthians 16:13-14}
