Paul writes to Timothy in 1 Timothy 1:5, and tells him "The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith." In context, he's encouraging Timothy to stay at Ephesus so he may combat false doctrine. He tells Timothy that our goal is to love people with sincere faith. Our goal is for them.
As believers, our goal in preaching and witnessing to people is not a gold star in heaven. Our goal in correcting false doctrine is not the satisfaction of winning an argument. Instead, our goal is to love people. The challenge is that loving people is much harder than we often think because people aren't always lovable. People will sometimes irritate us, hurt us, or misunderstand us. And though loving people can be difficult, it is possible with God's help. Loving people is a MUST in God's eyes (see 1 John 4:20).
So, how can we love with sincerity? The key is prayer and self-examination. The psalmist said, Search me, O God, and know my heart; test me and know my concerns. 24. See if there is any offensive way in me; lead me in the way everlasting (Psalm 139:23-24).
Our hearts can be deceitful (Jeremiah 17:9), and if we're not careful, we can easily stray away from sincere love. I've found that it's always important to ask why we do what we do. Are my actions focused on my personal benefit, or are they putting the advantage of others above mine?
Whatever we do for others, let us remember what our aim is. Our aim, our goal, is love that issues from a pure heart and a good conscience and a sincere faith. Before acting in love today, consider the attitude of your heart, consider your conscience, and consider your faith. Why am I doing what I'm doing? Am I doing it for them, or am I doing it for myself?
Our goal is to love people with sincerity. Who do you need to love with sincerity today?
