2 Corinthians 3:1-3 (NKJV)
1 Do we begin again to commend ourselves? Or do we need, as some others, epistles of commendation to you or letters of commendation from you? 2 You are our epistle written in our hearts, known and read by all men; 3 clearly you are an epistle of Christ, ministered by us, written not with ink but by the Spirit of the living God, not on tablets of stone but on tablets of flesh, that is, of the heart.
Does your heart reflect your self-control? The last fruit of the Spirit is self-control. Others are always watching to see what Christians do in situations. Your best witness might be how you act in situations. They may see that you put others first in situations. They may see that you do not follow but that you lead by example.
Your example may also show that you do not overreact. Someone may do something unjustly to you and yet you take it in stride. An unexpected circumstance happens yet you do not get excited but instead you pray.
Yet as you pray in an area of concern, others may see your self-control. It may show that you allow God to put into place all the pieces you need for you to make a proper decision and this may be a witness. They may see the decision you make in being obedient to God may have you move or change paths that alters your comfort zone. He wants to draw you into His comfort and for you to accept His will not only for others to see, but also for Him to get all the Glory.
God always has a plan and we need to pray and prepare to seek His will and receive His blessings. So, seek His will and know He loves you. When we allow Him to be Lord of our lives, He will bless us, and others will want what you have and that is His love. His love leads to self-control.
