1 Corinthians 4:5 - Therefore judge nothing before the appointed time; wait till the Lord comes. He will bring to light what is hidden in darkness and will expose the motives of men’s hearts. At that time each will receive his praise from God.
There will be a time when we are called on to judge others according to their deeds. That time is not now. Now we are to Love others and always think the best of them. As we look at this verse we see part of the reason why we cannot judge now. When we look at people and judge them we are only seeing actions. All we can see is the outward appearance of things; we cannot see the heart.
There is no way for us to truly know the motive behind someone’s actions. Someone may do something that seems totally messed up from our point of view, but that doesn't necessarily mean it is wrong. With the right heart behind it a wrong action may not be sin.
There will be a day when Christ will return and bring light to everything. Darkness will be chased away and every secret will be revealed. Until then we are not supposed to judge others.
We can however take a look at our own lives. That is where you can truly make a judgement call. You know your heart; you know the motives behind your actions. Are doing things for the right reasons? Are you looking for approval and acceptance from men or God?
If you are always looking to man for approval and acting in a way that will make you look good on the outside you will often miss God’s will. Your focus needs to be on God. He should be the reason we do the things we do. God says that if we seek Him first He will take care of the rest of our lives. Don’t worry about your actions. If your heart is right, then your actions will be also.
