Acceptance is being patient and enduring. Don’t upset a friend because you cannot accept something about them. We can continue to assist them by shining our light, but we should not think more highly of ourselves than we ought to. If we are loving the same Lord then what is the problem? Should we allow trivial differences to bring problems in our relationship with others? Jesus came to bring us love, not rules and regulations.
Always keep the gospel first and foremost in your mind.
For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned. For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another. Romans 12:3-5
We have the divine word of God spoken in Jesus Christ and through the power of the Holy Spirit. In Acts 13, Paul went on to speak a word of encouragement. He said, "We tell you the good news: What God promised our fathers, he has fulfilled for us, their children, by raising up Jesus." How's that for a word of encouragement? God promised and God fulfilled the promise! Jesus was raised from the dead. God continues to work in and through us and because of God's great work in us, we can speak the Good News to others. We can speak a word of encouragement in the midst of a world that needs it so desperately.
