Paul tells us about love in his letter to the church at Corinth, and John adds a crucial element, which is that we know what love is because “Jesus laid down his life for us (1 John 3: 16).”
Love is sacrifice.
“If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him (1 John 3: 17)?”
This seems obvious, doesn’t it? If we have no compassion for others, especially for our brothers and sisters in the Lord, how can we claim to understand God’s love? We can’t because we actually do not know God’s love. We do not exist within God’s love.
John tells us not to only love with words, but with actions.
Yet, he also implies that we will fail, that our hearts will condemn us because we will not always understand and live within God’s love. In a real sense, this is because we are not God. We are incapable of living up to God’s expectation of perfection. Simply put, while we dwell on earth, we are not yet perfected. Therefore, John tells us “how we set our hearts at rest in his presence whenever our hearts condemn us (1 John 3: 19-20).” We set our hearts at rest because “God is greater than our hearts, and he knows everything (1 John 3: 20).”
Since God knows everything and yet does not condemn us, then we may be at peace.
What a stunning paradox.
