1 Corinthians 13:13 (NKJV)
“And now abide faith, hope, love, these three; but the greatest of these is love.”
In many ways, christendom has placed emphasis on the wrong things. These things might be good things, but when they are too important, they become stumbling blocks.
Some focus on preaching style, some focus on their Facebook persona, some focus on their degrees, some focus on their spiritual gifts, some focus on speaking in tongues, some focus on how they dress, and some focus on their doctrinal distinctions.
What does this do? It all produces pride. Because ultimately we start to judge ourselves by ourselves and we become our own standard. However....when we judge ourselves by Jesus, we must conclude that love is the principle thing.
The Bible says that the greatest and most important part of our lives is love. From experience I tell you, when you are filled with God's love (the Holy Spirit/Spirit of Christ/walking in the Spirit), you will automatically be an obedient, happy Christian, but if you are focusing on whatever you think is important, love will dry up.
You see, in Galatians 5:22 we read that love is the very first thing listed in the fruit of the Spirit. Not preaching, dress, doctrine, tongues, or any other good thing. If we are not careful to focus on walking in God's love, we will start to condemn those who do not fit our mold. When we walk in love, we have compassion, and when we have compassion, it is much easier to forgive, to witness, to be patient with the lost, and other groups who disagree with us.
So ask God to fill you with His love/Spirit...and remember that God IS love (1 John 4:8;16). Judge yourself by God's love, not what you think. When we do this, we will see 1 Corinthians 13 start to flow out of us rather than trying to make it happen in us.
