Christ absolutely commands His followers to love everyone — including those whose beliefs or chosen faith (or lack of beliefs or faith, as the case may be) do not align with God’s Word.
Jesus said that the world will know we are Christians not by our theology, not by our political party, but, rather, by our LOVE.
Jesus went to so far as to command His followers to love and show love to even their enemies, the very people who hate and despitefully use them.
He led by example: He showed His love, mercy, forgiveness, and grace to others — even those who mocked Him, spat on Him, beat Him, and crucified Him. He showed love to everyone, even while He was suffering and dying on the cross for our sins.
There is no place for hating other people in the life of a Christian. It is forbidden. It is wrong. It is sin. And, it will keep people out of Heaven.
However, showing love to, respect for, and kindess toward other people does not require us also to accept or embrace specific beliefs, thoughts, ideas, actions, doctrines, and practices that Scripture identifies as being wrong, sinful, and contrary to God’s will for His people.
God’s Word is very clear that there are spiritual forces of darkness that have rebelled against God and have exalted themselves against the Truth of God. It is filled with warnings about the temptations and deceptions that these evil spiritual forces will bring.
It is not against people, but against those forces of darkness and the deceptions that they perpetrate, that Christians are commanded — through the authority of Christ and the power of Holy Spirit, to stand firm, and fight.
